When a partical moves in a circular path its speed remains constant but its direction is always changes continuously. Therefore, we can say that circular motion is an accelerated motion.
Since, the magnitude of velocity is constant ,a component of acceleration along the direction of velocity is zero . Thus,acceleration is always perpendicular to the direction of velocity . As the direction of velocity is along the tangent of the path. Hence, the direction of acceleration is always towards the centre of the path. These acceleration is called centripital acceleration.

CENTRIPETAL ACCELERATION :
In uniform circular motion, the direction of velocity continuously changes. Hence, there is an acceleration whose direction is towards the center of the path. This is called CENTRIPETAL ACCELERATION.
CENTRIPETAL ACCELERATION = v^2 / r
Where v = linear velocity, r = radius.
