The expression represents the centripetal acceleration of the object is, a = v²/r

Explanation:

The centripetal force is experienced by the body when the body moves in a curved path.

Let the object of mass 'm' moves in a circular path of radius 'r' with the tangential velocity 'v'. Then the centripetal force acting on the body is given by the expression,

                                         F = mv²/r

This centripetal force is directed along the radius of the circular path.

Comparing the centripetal force with the linear force equation,

                                        F = ma

And comparing the terms, it is clear that

                                         a = v²/r

Hence, the expression represents the centripetal acceleration of the object is, a = v²/r
