PPT-Chapter 6: Circular Motion and Gravitation

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. 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.. 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. . 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. Angular Measure, Angular Speed,. and Angular Velocity. Bellwork. . 1. A tube is been placed upon the 1 m-high table and shaped into a three-quarters circle. A golf ball is pushed into the tube at one end at high speed. The ball rolls through the tube and exits at the opposite end. Describe the path of the golf ball as it exits the tube.. 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?. Circular Motion Lab Results. Part 1: Radius’ effect on velocity. Mass, centripetal force kept constant. Part 2: Mass’ effect on velocity. Radius, centripetal force kept constant. Part 3: Force’s effect on velocity. 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. © 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.. 5-1 Uniform Circular Motion. Uniform Circular Motion. : The motion of an object traveling at a constant (uniform) speed on a circular path. 5-1 Uniform Circular Motion. Since we are dealing with object moving in a circle, it is convenient to talk about the . 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.. 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..
