Question

Define centripetal acceleration. Derive an expression for centripetal acceleration of an

object in uniform circular motion in a plane. What will be the direction of the velocity

and acceleration at any instant?​

Answer 1

Centripetal acceleration is the rate of change of tangential velocity. The net force causing the centripetal acceleration of an object in a circular motion is defined as centripetal force. The direction of the centripetal force is towards the center which is perpendicular to the velocity of the body.
