PPT-More Centripetal Force Problems

We have already seen the forces acting on a mass moving in a horizontal circle now lets see how this differs from a mass moving in a vertical circle Draw the forces acting on a mass on a string being spun in a vertical circle at the . 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. physics centripetal force needed to keep the ball moving in the circle at constant speed. Does the forceexerted by the string on the ball do work on the ball in this situation? Explain. Physics 110 Pr Equations:. Academic Vocabulary:. Centripetal force. Centripetal acceleration. Circular motion. Tangential velocity. Inverse square law. Gravitational constant. Universal gravitational force. Weightlessness. 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: . 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 . Uniform circular motion and Universal Gravitation. Centripetal Acceleration & Force. Centripetal Acceleration & Force. This unit we will investigate the special case of kinematics and dynamics of objects in . Calculate angular speed in radians per second.. Calculate linear speed from angular speed and vice-versa.. Describe and calculate centripetal forces and accelerations. .. Motion . in Circles. We say an object . Test Tomorrow. The term “EU” stands for. . Estados. . Unidos. Economic Union.

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.
