PPT-Circular Motion and Gravitation

Can you change your velocity while not changing your speed v F Consider the above situation According to Newton S econd law what must the object be doing It is accelerating so the velocity must be changing. Chapter 5. Kinematics of Uniform Circular motion. An object that moves in a circle at constant speed, v, is said to be under uniform circular motion. . The magnitude of velocity remains constant.. The direction of velocity changes continuously.. 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.. 5.1 . Uniform Circular Motion. DEFINITION OF UNIFORM CIRCULAR MOTION. Uniform circular motion is the motion of an object . traveling at a constant speed on a circular path.. 5.1 . Uniform Circular Motion. Equations:. Academic Vocabulary:. Centripetal force. Centripetal acceleration. Circular motion. Tangential velocity. Inverse square law. Gravitational constant. Universal gravitational force. Weightlessness. Curves. Forces act in straight lines. An object will move in a straight line if there is NO force acting on it or if the net force acts in the direction of the motion.. BUT, what if the net force acts at an angle to the motion?. Supported by . UBC. Teaching and Learning Enhancement Fund . 2012-2015. Department of . Curriculum and Pedagogy. FACULTY OF EDUCATION. Question Title. Question Title. Circular Motion. http://. nwsphysics99.blogspot.ca. Newton’s Law of Universal Gravitation. Newton Did not discover gravity, but he did discover gravity was universal. In other words, everything pulls on everything else.. States:. Every object attracts every other object with a force that for any two objects is directly proportional to the mass of each object, and indirectly proportional to the distance between them.. 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.. © 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.. Uniform Circular motion. For an object moving on a circle at constant speed. The . speed is constant. , but the . direction is not. Acceleration is a change in velocity, but speed is constant. The change in velocity is only in its direction. 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. (missions Apollo) . TERRE - LUNE .
