Vedclass · Answer

(C) In uniform circular motion,the speed of the object remains constant,but the direction of motion changes at every point. Since linear velocity is a vector quantity (having both magnitude and direction),it changes continuously. Acceleration in circular motion is centripetal acceleration,which is directed towards the center of the circle. As the direction of the object changes,the direction of this acceleration also changes continuously. Since force is related to acceleration by $F = ma$,the direction of the force also changes continuously. However,the angular velocity $\omega$ remains constant because the rate of change of angular displacement is constant in uniform circular motion.
