PPT-Chapters 11-13 Review Force, Motion, Dynamics, and Fluids

1 A system of objects that are not moving with respect to one another Used to determine the motion of an object Frame of Reference 2 If you were measuring the length of a lunch tray you would most likely label it with the following unit. Chapter 5. Learning Objectives- . Circular motion and rotation . Uniform circular motion. Students should understand the uniform circular motion of a particle, so they can:. Relate the radius of the circle and the speed or rate of revolution of the particle to the magnitude of the centripetal acceleration.. - Class . 13. Today:. Dynamics . in Two Dimensions. . Dynamics of Uniform. Circular Motion. Fictitious. Forces. Pre-class Reading Quiz. (Chapter. 8). Last day I asked at the end of class:. A ball is whirled on a string in a vertical circle. As it is going around, the tension in the string is. 3. Applications of Newton’s Laws in 1 dimension. Free Fall. Motion in a Fluid. Spring motion. Molecular Dynamics. Free fall. Acceleration = g = 9.8 m/s. 2. = constant. Constant acceleration implies constant force = weight. Pressure.. A measure of how much force is acting on a certain area. How concentrated the force is. Pressure is force divided by area.. Pascal.. The unit used to measure pressure. One . pascal. is the pressure exerted by one newton of force on an area of one square meter.. What is motion?. Motion . is . when an object changes its . position. .. Motion . can be represented mathematically through calculations of . speed, velocity, and . acceleration. Motion is . when an object changes its position. Forces. We have learned that forces . either pushes or pulls.. They come in many varieties:. Gravity & Normal. Kinetic & Static Friction. Electrical & Magnetic. Air resistance. Tension. Nuclear Force. Dynamics is the study of force and its effect of motion.. A force is a push or pull that can change the inertia of an object.. Newton’s First Law of Motion. Every body continues in its state of rest or motion, unless acted upon by a force.. You will need your CID for the exam- Memorize it!!!!!. Other Reviews. Fri 1-3 108 MARB. This is a weekly review, so feel free to come at any time during the semester.. We cover general concepts as well as problems from the book and from the homework.. 1. Changing Units. Speed of a car is 80 miles/hour. What is it in m/s. Multiply by 1 so units cancel and correct units are left. In units of m/s: {80 miles * (5280 feet/mile)*(1 m/3.28 feet)}/hour. Forces and Motion Chapters 11-12 Frame of reference A system of objects that are not moving with respect to one another To describe motion accurately and completely, a frame of reference is necessary.

If you get the ball in the hoop, each person on your team wins a piece of candy. Dynamics I Forces & Newton’s First Law 4 Natural Forces Gravity : acts between all masses in the universe and has “infinite” range Electromagnetic (EM) Force : acts between electrically charged particles and “magnetically charged” poles Force and Motion Basketball Review Game Game Rules If your team gets the question right, you get a chance to shoot the ball into the hoop. If you get the ball in the hoop, each person on your team wins a piece of candy. the . process of moving . or . changing . places . or position. Anything you do while moving is motion.. Fact: Speed is a major type of Motion. Determining motion. In order to determine motion you must know direction and speed.
