What is the difference between tangential and radial acceleration for a point on a rotating body?

Solution 3DQ Step 1 of 3: For a body performing uniform circular motion, the centripetal force acts on it. Due to which it has the centripetal acceleration or the radial acceleration is the rate of change of tangential velocity as in figure below When an object moves in a circle with uniform speed, it has a centripetal acceleration , directed toward the center. This centripetal acceleration is directed along a radius so it may also be called the radial acceleration. The expression for the centripetal acceleration(a )c, 2 ac= v r Where v are the tangential velocity of the object and r is the radius.
