Both acceleration and velocity change

Vedclass · Answer

(C) In uniform circular motion,the speed of the particle remains constant,but the direction of motion changes continuously at every point along the circular path.Since velocity is a vector quantity (having both magnitude and direction),a change in direction implies a change in velocity.Furthermore,the acceleration in uniform circular motion is the centripetal acceleration,which is directed towards the center of the circle.As the particle moves,the direction of this centripetal acceleration vector also changes continuously to remain directed towards the center.Therefore,both velocity and acceleration change in direction,even though their magnitudes remain constant.
