then you must include on every digital page view the following attribution: Use the information below to generate a citation. i though my reasoning was pretty straight forward on why i approached it that way.the tension would be on the rope (or whatever is pulling it) in between the tug boat and the coal boat. The system of interest here is the barge, since the forces on it are given as well as its acceleration. Whatever method is used, the goal is always the same: to create enough force to move the much larger ship through the water. This friction slows down the barge and makes it harder for the boat to move forward.When a tugboat pushes a barge from behind, however, there is less friction between the barge and the water. Dec 31, 2011. If youve ever taken a water ferry, you will appreciate the fact that even when the boats are moored to the bollards at the jerry, they keep bobbing up and down, and sometimes even sway sideways. Since the applied forces are perpendicular, the, A traffic light is suspended from two wires. The first tugboat exerts a force of 2.7105 N2.7105 N in the x-direction, and the second tugboat exerts a force of 3.6105 N3.6105 N in the y-direction. Towboats in line-haul service operate 24/7 and have the latest in navigational equipment, such as color radar, GPS systems, electronic river charts, and specialized radio communications. (c) Only forces acting on the system are shown here. In normal conditions, a barge could go 10 or 11 feet below the water. Common dumb vessels include oil barges, platforms, and disabled ships, among others. They also act as salvage boats. But a lot depends on where it happens. A dumb vessel does not have its own propulsion system. What If You Jumped Out Of An Airplane Into The Sea Without A Parachute? (b) Some of the forces involved. Tug boats play an important role in keeping the Mississippi River running smoothly. These serve also to illustrate some further subtleties of physics and to help build problem-solving skills. Indirect towing can later be accompanied by direct towing. The uncertainty of movement due to water currents in narrow areas, such as harbors and ports, leave little room for course correction. Does the tug boat connect to the coal barge and the coal barge to the other barge? A Beginners Guide. Order Now. Calculate the scale reading: (a) if the elevator accelerates upward at a rate of 1.20 m/s21.20 m/s2, and (b) if the elevator moves upward at a constant speed of 1 m/s. Generally, these ASD tugboats have a couple of propulsion units placed in the turning nozzles. The arrows are approximately correct for when the elevator is accelerating upwardbroken arrows represent forces too large to be drawn to scale. Question 2. Connected to the Pearl River, the canals are kept at a constant level by a lock system, spillway and . An example of seagoing tugboat is given in Figure 1. How is a tow boat different from a barge? But low water caused by a severe drought means some barge lines are loading at no more than eight feet. Solving for FsFs gives an equation with only one unknown: No assumptions were made about the acceleration, and so this solution should be valid for a variety of accelerations in addition to the ones in this exercise. Facebook. In terms of power and water resistance, it is more efficient to push rather than pull a barge. Amazon and the Amazon logo are trademarks of Amazon.com, Inc. or its affiliates. Tugs also help guide barges into and out of locks, and can provide extra power when a barge needs to be pulled against a strong current. The first tugboat exerts a force of \(2.7 \times 10^5 \, N \) in the x-direction, and the second tugboat exerts a force of \(3.6 \times 10^5 \, N \) in the y-direction. And because theyre smaller than the barges theyre pushing, they can maneuver around them much easier. When a tug with a barge behind it enters restricted waters the crew will pull in the tow line and perhaps lash the barge to the side of the tug boat, thus making the tug and barge one vessel. A Tugboat or Tugboats are a special vessel used mainly near the harbor and ports to assist in docking of the ships. Conventional tugboats the oldest types of tugboats. yes I've sketched and drawn free body diagrams, would the other rope attached to the coal barge be creating a force of friction too? sweden, stockholm, lake malaren, tugboat pushing barge, city in background - tugboat pushing barges stock pictures, royalty-free photos & images Tug boat pushes a barge down the East River and out in the bay on November 3, 2017 in New York City. The different types of tugboats propulsion system or different configurations of tugboats propulsion systems can provide higher power with fewer energy consumptions. They also have a smaller environmental impact than larger ships, as they produce less pollution. Barges in tow and/or boat bumping (hitting an object) when entering a lock or landing in a fleet. Answer (1 of 3): "Tow Boat" is the correct term for vessels that are used to push a string of barges up and down rivers. For example, the average barge tow contains 15 barges and can carry as much freight as a freight train three miles long or a line of semi-trucks 35 miles long! Invention Of Wheel: How Was The Wheel Invented? Cornell Maritime Press, Russell P. A., Jackson L.,& Morton T. D. (2018). . The tugboat pushes against a barge. Integrate concepts from kinematics to solve problems using Newton's laws of motion. Thanks to that, the properties of seagoing tugboats have the capability for performing operations like towing, pushing, search-salvage, backup, anchor handling, supply transports, and attract barges on open ocean waters. The force is created by the engines turning giant propellers. Consider the following example. In addition, the ice-class tugboats can perform ice-breaking operations too. This means that the scale is pushing up on the person with a force greater than his weight, as it must in order to accelerate him upward. The most common type of conventional tugboats is equipped with a diesel main engine, a single propeller and a classic rudder. industry - tugboat stock illustrations. The tow boat is the stern of the vessel, and the front barge is the bow. Maupun kapal-kapal yang tidak memiliki penggerak sendiri. We are given the initial and final velocities (zero and 8.00 m/s forward); thus, the change in velocity is v=8.00 m/sv=8.00 m/s. There are several movable and controllable blades on this circular disk. The answer has to do with physics.Tugboats push their barges because its more efficient than pulling them. RM EFYKJW - A powerful type of towboat called a pusher, pusher boat or pusher tug pushes full and empty cargo barges up the lengthy Mississippi River in the USA. Push Boat a boat designed for pushing barges. Listing the givens and the quantities to be calculated will allow you to identify the principles involved. If these are available for the specific topic, you should refer to them. Consider the following example, where the angles are not equal; slightly more trigonometry is involved. A tugboat is not only restricted to guiding large vessels in narrow water channels. Otherwise, dumb barges must be towed by tugs, or pushed by pusher boats. The tug will use its engines to move the vessel forward.If a tug is pulling, it is because the vessel being towed is small enough to be pulled. They can be classified as follows: Conventional tugs use a tow line, also known as a hawser to pull big vessels (Photo Credit : Nightman1965/Shutterstock). It can be understood by the total horsepower and bollard pull capacities. Why are the three different surface tensions in the directions shown? Credit: NASA Before each test, Pullman, Tugboat Pilot Grover "Shu-Shu" Bennett, Marine Maintenance Technician Dwight Strahan and a general helper push barges of super-cool liquid hydrogen and liquid oxygen through the canal system at Stennis. The players mass is 70.0 kg, and air resistance is negligible. In the United States above St. Louis on the Upper Mississippi River and on other rivers such as the Illinois, Ohio, Arkansas, Tennessee and Cumberland, boats can handle only up to 16 barges including a "hip" barge due to the size of lock chambers. In the United States above St. Louis on the Upper Mississippi River and on other rivers such as the Illinois, Ohio, Arkansas, Tennessee and Cumberland, boats can handle only up to 16 barges including a hip barge due to the size of lock chambers. Science Physics Two boats push on a barge at different angles. These boats usually operate on rivers and inland waterways. In addition, there are relatively new versions of ASD tugboats which have arranged one or more Z-Drive unit in amidships or fore of the tugboat. Aerial view of tugboat in leaving port for pilotting. The type of tug, propulsion system and bollard pull is the most important properties of a tugboat. Due to the nature of the payload on barges, it is easier to push, rather than tow them. One tugboat pulls on the barge with a force of magnitude F 2 = 4235 units of force at 2 = 25 above the line AB and the other tugboat pulls on the barge with a force of magnitude F 1 = 5376 units of force at 1 = 42 below the line AB. Together, the set of barges is called "the tow". When an elevator accelerates downward, aa is negative, and the scale reading is less than the weight of the person, until a constant downward velocity is reached, at which time the scale reading again becomes equal to the persons weight. This can be solved for the magnitude of the drag force of the water FDFD in terms of known quantities: The direction of FDFD has already been determined to be in the direction opposite to FappFapp, or at an angle of 5353 south of west. FDFD is in the opposite direction of FappFapp, since it acts to slow down the acceleration. The system of interest is the traffic light, and its free-body diagram is shown in Figure 4.22(c). This worked example illustrates how to apply problem-solving strategies to situations that include topics from different chapters. In a tug assist, one or two tugboats meet the larger ship while it is still outside the port. To disassemble tow. Can We Really Build Cars That Run Only On Water? https://openstax.org/books/college-physics-2e/pages/1-introduction-to-science-and-the-realm-of-physics-physical-quantities-and-units, https://openstax.org/books/college-physics-2e/pages/4-7-further-applications-of-newtons-laws-of-motion, Creative Commons Attribution 4.0 International License. Smaller boats are used in harbors, fleeting areas and around locks while larger boats operate in "line-haul" operations over long distances and between major ports. Therefore, a tugboat can be designed for performing one or more functions. Tug and barge specification - to ensure among others: vessel age, size, horsepower, capacities, limitations etc. The directions and magnitudes of acceleration and the applied forces are given in Figure 4.21(a). the physics and finesse of handling of ships and barges with a tugboat; CONCLUSION: LPS, as caretaker, and Luna, as an NHL, offer a unique experience for utilization of a cultural resource. Giu 11, 2022 | how to calculate calories per serving in a recipe. The answer has to do with physics. This makes them agile and more suited to handling container vessels. The tires cushion the impact when the hull accidentally or deliberately (as in the case of a pushing tug) contacts a dock or another vessel. Tug boats for sale on Boat Trader are offered at an assortment of prices from a sensible $10,644 on the more affordable end all the way up to $2,589,450 for the bigger-ticket boats. Solve the problem using strategies outlined in the text. What Physics Are Involved In The Working Of Sailboats? A conventional tugboat series profile view is given in Figure 4. Ocean tugs are engineered to work in deep sea settings. Along with the primary purpose of towing the . aerial top view tugboat pushing container ship to quayside for unload container at crane bridge for logistics, import export, shipping or transportation. (b) The free-body diagram for the ship contains only forces acting in the plane of the water. Tug, barge and crew certification - to ensure tug, barge and crew comply with required standards. With approximately one-third of the length from the bow location of this system on the tugboat, the positive turning moment is always present. If the mass of the barge is 5.0106 kg5.0106 kg and its acceleration is observed to be 7.5102 m/s27.5102 m/s2 in the direction shown, what is the drag force of the water on the barge resisting the motion? Fungsi utama tug boat adalah : Menarik atau mendorong kapal-kapal yang berukuran besar yang kesulitan bersandar di dermaga. The OpenStax name, OpenStax logo, OpenStax book covers, OpenStax CNX name, and OpenStax CNX logo The key characteristics of the conventional tugboats are the high reliability and efficiency of power expressed in the force of bollard pull. What Is The Maximum Force The Locust Exerted on The Plate? Bloomsbury Publishing, Reeds Vol 8 General Engineering Knowledge for Marine Engineers (Reeds Marine Engineering and Technology Series), The Singularity Is Near: When Humans Transcend Biology. arrangement; fender types and fender arrangements affect the efficiency of the tugboats bollard pull and manoeuvre capabilities according to their operations and service areas. Thus, small yet extremely powerful boats are deployed to help assist larger vessels. What are the major organs of the respiratory system and their functions? The DELTA QUEEN is over 600 feet long and has a diesel engine that produces over 12,000 horsepower!Thats enough power to push 33 loaded coal barges weighing a total of over 27 million pounds! An example of river tugboat is given in Figure 2. +T - the unknown force that the tug boat exerts. A towing vessel is considered to operate in California if it is within Regulated California Waters (within 24 nautical miles of the coastline). You will find these techniques for integrated concept problems useful in applications of physics outside of a physics course, such as in your profession, in other science disciplines, and in everyday life. Why Do People Indulge In Extreme And Dangerous Sports? Tie Down Lids. The main function of the towboat is to push the barge. Drag Force on a Barge. The tugboat pulls the two barges with an acceleration of 0.030 m/s2. 2 Mtb-8000 kg mi -1500 kg Mtb 6000 kg m 2000 kg Mub . OpenStax is part of Rice University, which is a 501(c)(3) nonprofit. Larger vessels berth at ports assisted by tugboats, as unpredictable movement in the water can result in heavy damages (Photo Credit : CANARAN/Shutterstock). The barge connected to the tugboat, carrying coal, has an inertia of 2.0 105 kg, and the other barge, carrying pig iron, has an inertia of 3.1 105 kg.The resistive force between the coal barge and the water is 8.0 103 N, and the resistive force between the pig iron barge and the water is 1.0 104 N . Therefore, the net external force is in the same direction as FappFapp, but its magnitude is slightly less than FappFapp. $550. How many barges can a tug boat push? Please show your reasoning. Twitter. Models with more power can accommodate motors up to 680 horsepower, while more compact utility models may have as low as 10 horsepower engines on them (although the . Lets find out! When indirect towing is needed, the tugboat acts as . Tugboats are quite strong for their size. Generally, one or two multidirectional propulsion systems combination is preferred for tugboats, that works in the cycle of 360 degrees on the principle of two vertically built propulsion mechanism with rotating blades. Here are some tips for sharing the water with them. In recent news, a huge shipping container infamously held up maritime traffic in the Suez Canal. Kira Volkov/Dreamstime. *Regulation - any/all barges less than 200 in length and less than 35 in width. The positive direction is to the right. Heartland Barge Brokerage services offers a great selection of reliable and quality used Push Boats for sale for all your commercial needs. While excavators were deployed to remove sand around the hull, tugboats were deployed to pull the ship back onto course. This allowed each barge to carry approximately 2,000 tons of coal (times six = 12,000 tons times 2000 pounds . Crews continue to maintain boom deployed and remain focused on environmentally sensitive areas. We can do this, as usual, by applying Newtons second law, From the free-body diagram we see that Fnet=FswFnet=Fsw, so that. high bollard pulls and deformed stern form which suitable for pushing barges. The whole tow, excluding the towboat, can easily be over 1,200 feet (370m) long and 200 feet (61m) wide, covering over 6 acres (2.4ha) and holding thousands of tons of cargo. In order for a tugboat to tow or push a barge there must be a hawser (a rope or chain) connecting the two vessels. How fast will a walk-behind trencher dig? buy a product on Amazon from a link on here, we get a small percentage of its Tugboats have one or more strong winches for towing operations and a high manoeuvre capability design with a durable structure, which have less centre of gravity to avoid capsizing. here we have our barge being pulled along by our horse appear With a force of 7900 newtons at an angle of 18. The flat hull design of river tugs enables them to push large barges at sea, but makes them unsuitable for ocean operations (Photo Credit : KennStilger47/Shutterstock). When a tugboat pulls on a rope that is attached to the front of a barge, the force that the boat exerts creates friction between the bottom of the barge and the water. "The large tug is capable of towing up to five 120-foot barges loaded to their maximum weight of 733 long tons (2,200 pounds) per barge," Chief Warrant Officer Darren Reese explains. Coupling where the sides of barges in the tow meet. These boats tend to be limited to 5,000 horsepower (3,728 . Finding Angular acceleration of the spool with the rope exerting a force on it. Save my name, email, and website in this browser for the next time I comment. The tug, powered by twin EMD 12-645 diesels, was towing a barge back and forth between Alaska and Washington, burning about 80,000 gallons of fuel for each 2,000-mile round trip. Tugboats are generally classified according to their work duties and the characteristics of the waters in which they operate. They are used to assist these ships in places where they are unable to maneuver themselves, such as narrow water channels and ports. The Port of Pittsburgh itself is the fourth busiest inland port in the nation. then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, You are using an out of date browser. In addition, these propeller units are known as Z-Drive units due to the shape of the nozzles. The only forces acting on the person are his weight ww and the upward force of the scale FsFs. Is Mathematics An Invention Or A Discovery? This can cause the ship to collide and result in expensive damage. Tugboats are small, powerful boats capable of steering large ships by pulling or pushing them. the 180 ft barge, the 230 ft barge and so on. But can you predict what you would see on the dial of a bathroom scale if you stood on it during an elevator ride? It is square and has two tall structures designed to push the square shape of a river bar. A standard barge is 200 feet long, 35 feet wide, and when loaded to its 1500-ton capacity needs a nine-foot depth of water to float. Instead of fixing propeller fans to the hull of the ship, they are fitted to a motorized pod that can be rotated by a horizontal angle, known as the azimuth. The masses of the tugboats and barges, and the accelerations of the systems are given for each case. By making a few modifications to their bow and hull, they can also be used for ice-breaking operations. These boats, known as tugs or tugboats, serve several important functions. Sanmar Boaay ASD tugboat series profile view is given in Figure 5. Associates Program, affiliate advertising program designed to provide a means 1 are suitable and adequate for intended cargo and voyage. That is a substantial difference of 5 l/h x 3000h = 15000l x 1.3/liter 19500. Intercon Advantages. You have assumed there are only two forces acting on the barge - is that a sound assumption? Since the 1950s, tug watchers have been on a restricted diet of commercial barge tows on New York . The tug will use its engines to move the vessel backwards. Tugboat pushing a barge up a river. According to Newtons third law FpFp and FsFs are equal in magnitude and opposite in direction, so that we need to find FsFs in order to find what the scale reads. Now, what happens when the elevator reaches a constant upward velocity? According to the Tugboat Enthusiasts Society of the Americas, a tugboat has the main job of pulling larger ships to dock. The systems of tugboats and barges are accelerating at different rates to the right. Ranking Task Exercises in Physics ii Introduction Library of Congress Cataloging-in-Publication Data Ranking task exercises in physics / edited by Thomas L. O'Kuma, David P. Maloney, Curtis J. Hieggelke. Clearly, the greater the acceleration of the elevator, the greater the scale reading, consistent with what you feel in rapidly accelerating versus slowly accelerating elevators. Is The African Continent Splitting In Two? There is a type of towing by 'Notch' where the tug can be secured in a notch at the stern of a vessel that has a specifically designed cavity. The barge is pulled by a tugboat, which is attached to the front of the barge via a towline. Jan 11, 2023 OpenStax. The story of these tugs started with steam-powered tugboats and with the development of initial combustion engines, steam propulsion abandoned the diesel engines having one or more propellers. Some crafts can even attach to the sides of these vessels. With direct towing, the tug is pulling the vessel straight ahead, likely due to the ship not having the ability to propel itself. Tractor tugboats are equipped with the drive units (Voith Schneider Propeller or ASD) located in the bottom of the vessel, approximately one-third of the length from the bow. What are Tug Boats - Different Types And Uses. Break up Tow. They are still serving all the world ports successfully. Tugboats with reinforced hulls are deployed on ice sheets to precede bigger vessels (Photo Credit : wiklander/Shutterstock). Take your own here and learn something new and perhaps surprising. This was a world record at the time for the most barges ever pushed at one time. Tow boats are shallow draft vessels and not designed to use in coastal or off shore waters. However, they are strong structures assisted by powerful propulsion systems that are fitted either towards the bow or directly at the stern of the ship. The strongest tugboat in the world, the Island Victory, has an engine capacity of 8,000kW and a max bollard pull of 474 tons! Voith Schneider Propeller (VSP) are propeller units that combine propulsion and steering in a single unit and provide the propulsion of the ship by rotating a circular disc placed on the bottom of the hull. Because the propulsion system is always in front of the tow. A tug, or more commonly a tugboat, is a secondary boat which helps in the mooring or berthing operation of a ship by either towing or pushing a vessel towards the port. With direct towing, the tugboat pulls the large vessel straight ahead. 1999-2023, Rice University. The first boat exerts a force of 6.9 x 105 N in the x-direction, and the second tugboat exerts a force of 4.7 x 105 N in the y-direction. Breast Coupling. As a result of documented fuel savings from these tests, Foss has outfitted other oceangoing tugs in its fleet with the FloScan equipment, according to company reports. | Sign up for the Science Times newsletter.] Larger vessels must be assisted in narrow water channels by smaller boats. The first tugboat exerts a force of 2.7 10 5 N in the x-direction, and the second tugboat exerts a force of 3.6 10 5 . The Voith Group, Wrtsil Encyclopedia of ship technology. A few hundred . Figure 4.23 shows a 75.0-kg man (weight of about 165 lb) standing on a bathroom scale in an elevator. Step 2. The propulsion systems found in tugboats come in three types: Fixed propeller with hinged rudder (Photo Credit : Tawansak/Shutterstock). A pusher, pusher craft, pusher boat, pusher tug, or towboat, is a boat designed for pushing barges or car floats.In the United States, the industries that use these vessels refer to them as towboats.These vessels are characterized by a square bow, a shallow draft, and typically have knees, which are large plates mounted to the bow for pushing barges of various heights. Visually, the tugboat has deep water propellers, a pointy bow and a deep hull. When a tow boat is pushing 20 or more barges, you need to think of the tow boat and the barges as a single vessel. Boats that traverse the Intracoastal Waterway (ICW) are commonly referred to as "ditch boats" or "canal boats". That is, Substituting the known values of mm and aa gives. The average tugboat can generate around 60,000 pounds of thrust. The term towboat arises from steamboat days, when steamboat fortunes began to decline and to survive, steamboats began to "tow" wooden barges alongside to earn additional revenue. TUGBOAT EXERTS ON LE A tugboat is pushing two barges (labeled 1 and 2) so that they speed up. Each barge has a carrying capacity equal to 60 semi trailers. A potential down-side on relying on the Tug Form for Towing Liability comes when the Tug/Push boat in question has a low Hull limit (such as a $50,000 tug boat moving an $800,000 barge; the Tug Form will only cover damages up to $50,000). In 2001, fifty-seven barges were pushed on the Ohio River near Cincinnati, Ohio. and other barge connect to the coal. It is square and has two tall structures designed to push the square shape of a river barge. The bow of the tugboat locks on that notch and starts to push the vessel. Multiple barges lashed together, or a boat and any barges lashed to it, are referred to as a tow and can have dozens of barges. unique traits of plants, animals and humans. When approaching problems that involve various types of forces, acceleration, velocity, and/or position, use the following steps to approach the problem: Step 1. When a tugboat pulls on a rope that is attached to the front of a barge, the force that the boat exerts creates friction between the bottom of the barge and the water. ifsi virtual learning. On June 8, 1986, thirty-three barges were successfully pushed at one time on the Mississippi River near Baton Rouge, Louisiana. Tug boats also have to be able to withstand the strong currents of the Mississippi River. Does a Tug 'Push' a ship off the jetty or does it 'Pull' a ship from the jetty? Daytime view of tug boat pushing barge down Mississippi River in front of Gateway Arch and skyline of St. Louis, Missouri as seen. Tugboats push their barges because it's more efficient than pulling them. It provides a quantitative reading of how much it must push upward to support the weight of an object. Mike Coon was preparing the boat for a voyage upriver, from Lock 8 on the Erie Canal to Amsterdam, N.Y. The second step is to solve for the unknown using familiar problem-solving strategies. Well, first of all, you need a very large towboat with a lot of power. These boats usually operate on rivers and inland waterways. *All above fleeting rates are on a per day basis. It is one of the leading propeller systems that provide the highest manoeuvrability in use today. May 26, 2020. Experts are tested by Chegg as specialists in their subject area. Harbour tugboats can be categorized according to the configuration or type of propulsion system. Multiple barges lashed together, or a boat and any barges lashed to it, are referred to as a "tow" and can have dozens of barges. To put that into perspective, that's the equivalent of six locomotives! Filial Cannibalism: Why Do Animals Sometimes Kill And Eat Their Own Young? The tooth pattern on the notch matches the tooth pattern on the tug, allowing for unlimited choices of draft on either vessel. However, ice-class tugboats have to meet the extra requirements like hull form requirements, balancing and extra power for ice breaking. The solution to the previous example also applies to an elevator accelerating downward, as mentioned. BoatingBuddy.com is a participant in the Amazon Associates Program. Ignore the effects of fluid friction. p. cm .- - (Prentice Hall series in educational innovation) Includes bibliographical references ISBN -13-022355-7 1. While this is still in a very nascent stage, it opens up the opportunity for tugboat use in both conventional and hazardous settings. So next time you see a tug boat pushing a barge, now you know why! This motor connects to a towing line carried aboard the vessel that is to be pulled. unique traits of plants, animals and humans. The biggest drawback of this system is that it is unidirectional, making it difficult to change course easily. In case of indirect towing, tugboats push the larger vessels on their hull, thereby rotating them around their vertical axis and changing their course. are licensed under a, Further Applications of Newtons Laws of Motion, Introduction: The Nature of Science and Physics, Introduction to Science and the Realm of Physics, Physical Quantities, and Units, Accuracy, Precision, and Significant Figures, Introduction to One-Dimensional Kinematics, Motion Equations for Constant Acceleration in One Dimension, Problem-Solving Basics for One-Dimensional Kinematics, Graphical Analysis of One-Dimensional Motion, Introduction to Two-Dimensional Kinematics, Kinematics in Two Dimensions: An Introduction, Vector Addition and Subtraction: Graphical Methods, Vector Addition and Subtraction: Analytical Methods, Dynamics: Force and Newton's Laws of Motion, Introduction to Dynamics: Newtons Laws of Motion, Newtons Second Law of Motion: Concept of a System, Newtons Third Law of Motion: Symmetry in Forces, Normal, Tension, and Other Examples of Forces, Extended Topic: The Four Basic ForcesAn Introduction, Further Applications of Newton's Laws: Friction, Drag, and Elasticity, Introduction: Further Applications of Newtons Laws, Introduction to Uniform Circular Motion and Gravitation, Fictitious Forces and Non-inertial Frames: The Coriolis Force, Satellites and Keplers Laws: An Argument for Simplicity, Introduction to Work, Energy, and Energy Resources, Kinetic Energy and the Work-Energy Theorem, Introduction to Linear Momentum and Collisions, Collisions of Point Masses in Two Dimensions, Applications of Statics, Including Problem-Solving Strategies, Introduction to Rotational Motion and Angular Momentum, Dynamics of Rotational Motion: Rotational Inertia, Rotational Kinetic Energy: Work and Energy Revisited, Collisions of Extended Bodies in Two Dimensions, Gyroscopic Effects: Vector Aspects of Angular Momentum, Variation of Pressure with Depth in a Fluid, Gauge Pressure, Absolute Pressure, and Pressure Measurement, Cohesion and Adhesion in Liquids: Surface Tension and Capillary Action, Fluid Dynamics and Its Biological and Medical Applications, Introduction to Fluid Dynamics and Its Biological and Medical Applications, The Most General Applications of Bernoullis Equation, Viscosity and Laminar Flow;
