Well I am now confused about centripetal acceleration. I have heard sometime ago that the change of acceleration is jerk. Let a body in centripetal acceleration change its velocity from 'v' to 'v1' in time 't'. The formula for centripetal acceleration is v^2/r. Let this acceleration be 'a'. Can the acceleration which originates from the point v1 be considered as v1^2/r? If it can be considered let this acceleration be 'a1'. Since the acceleration changes from 'a' to 'a1' in time 't', can the rate be called jerk? is my arguement correct?
