1 a What velocity must a car go around a 250 m radius corner to have a centripetal acceleration of 330 mss 287 ms b A centrifuge generates a centripetal acceleration of 3450 mss with a period of 00258 s What is the radius of the centrifuge 00582 m. 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.. and . Centripetal Force. Acceleration. Speeding up. Slowing down. Changing direction. . Think of spinning an object on the end of a string. How would you describe it to someone?. The easiest thing to say is that it moves in the shape of a circle.. 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. Equations:. Academic Vocabulary:. Centripetal force. Centripetal acceleration. Circular motion. Tangential velocity. Inverse square law. Gravitational constant. Universal gravitational force.

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.. This one’s going to be quick. Uniform Circular Motion. Uniform Circular Motion = an object following a circular path AT CONSTANT SPEED.. Why can we not say “at constant velocity”?. Definition: . Physics. Turning:. Turning counts as a form of acceleration because the direction of the velocity vector changes.. Turning requires a force that is perpendicular to the current motion of an object.. 5.3 Centripetal Force. From . Newton’s 2. nd. Law . we know that whenever an object accelerates, there must be a net force acting on the object to create the acceleration.. The net force causing centripetal acceleration is called .

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. .
