Centripetal acceleration is the rate of change of tangential velocity. Centripetal force is the net force causing the centripetal acceleration of an object in circular motion. The derivation of centripetal acceleration is very important for students who want to learn the concept in-depth. The direction of centripetal force is towards the center which is perpendicular to the velocity of the body.
