When an object makes a circular motion, it experiences both tangential and centripetal acceleration. Components of acceleration for a curved motion are radial and tangential acceleration.The tangential component occurs because of the change in the speed of traversal. It points along the curve in the direction of the velocity vector; also in the opposite direction.A tangential velocity works in the direction of a tangent at the point of circular motion. Henceforth, it always acts in the perpendicular direction to the centripetal acceleration of a rotating object. It always equals the product of angular acceleration with the radius of the rotation.
