Speed

Vedclass · Answer

(D) In uniform circular motion,an object moves along a circular path with a constant speed.Although the speed is constant,the direction of motion changes at every point on the path.Since velocity is a vector quantity (having both magnitude and direction),the change in direction implies that the velocity is not constant.Similarly,momentum $(p = mv)$ changes because velocity changes.Centripetal acceleration $(a_c = v^2/r)$ is directed towards the center of the circle,and its direction changes continuously as the object moves.Therefore,only the speed remains constant throughout the motion.
