PPT-11.2 Uniform Circular Motion

pg 551 Uniform Circular Motion When an object is moving in a circle and its speed the magnitude of its velocity is constant it is said to be moving with uniform circular motion The direction of the objects velocity is always tangent to the circle hence at the exhibition when going around in the crazy swirly ride your body wants to fly out of the ride. The Uniform Code includes provisions contained in Parts 1219 to 1228 of Title 19 of the New York Code Rules and Regulations the NYCRR and the provisions contained in the publications that are mentioned in Parts 1220 to 1227 Those publications includ 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.. Circular motion. We will be looking at a special case of kinematics and dynamics of objects in uniform circular motion (constant speed). Cars on a circular track (or on a curved road). Roller coasters in loop. express angular displacement in radians. . understand and use the concept of angular velocity to solve problems. . recall and use . v = r. ω. to solve problems. . describe qualitatively motion in a curved path due to a perpendicular force, and understand the centripetal acceleration in the case of uniform motion in a circle. .

Effect of force components . Components of force parallel and perpendicular to velocity have different effects.. © 2016 Pearson Education, Inc.. Goals for Chapter 6. To understand the dynamics of circular motion.. To study the unique application of circular motion as it applies to Newton. '. s law of gravitation.. Carry the motion over a distance. And. Change the type of motion. Transmission of motion. A group of simple machines can work together to make a . system. .. A system can transmit or carry the motion from one object to another.. Circular Motion. Objectives:. 1. Solve problems involving centripetal acceleration.. 2. Solve problems involving centripetal force.. 3. Explain how the apparent existence of an outward force in circular motion can be explained as inertia resisting the centripetal force.. 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. Uniform circular motion. What does the word “. uniform. ” mean here?. . constant radius. and . constant speed. . Velocity vector is tangent to the path at each instant, so direction of velocity vector changes all the time as the object moves in circle. . Circular . Motion. A. is towards the center.. V . is tangential to the motion. Speed is constant, . V. changes. A force directed towards the. center is what causes the. . acceleration (e.g. gravity, .
