Unformatted text preview: Chapter 5 Dynamics of Uniform Circular Motion 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 Let T be the time it takes for the object to travel once around the circle. v r T = 2 r 5.1 Uniform Circular Motion Example 1: A Tire-Balancing Machine The wheel of a car has a radius of 0.29m and it being rotated at 830 revolutions per minute on a tire-balancing machine. Determine the speed at which the outer edge of the wheel is moving. revolution min 10 2 . 1 min s revolution 830 1 3- = s 072 . min 10 2 . 1 3 = =- T ( 29 s m 25 s 072 . m 0.29 2 2 = = = T r v 5.2 Centripetal Acceleration In uniform circular motion, the speed is constant, but the direction of the velocity vector is not constant. 90 = + 90 = + = 5.2 Centripetal Acceleration r t v v v = r v t v 2 = r v a c 2 = 5.2 Centripetal Acceleration The direction of the centripetal acceleration is towards the center of the circle; in the same direction as the change in velocity. r v a c 2 = 5.2 Centripetal Acceleration Conceptual Example 2: Which Way Will the Object Go?...
