Please explain the differences between radial acceleration, tangential acceleration, angular acceleration and centripetal acceleration

Radial accn:- that accn. which is directed towads centre of the circular path(eg. centripetal accn.,centrifugal accn.)

tangential accn:- this accn acts if a body moves on a circular path with non uniform speed.(differentiating v = wr, we get a =wdr/dt+rdw/dt

i.e a(net) = v²/r + r(here v2/r is centripetal accn and r is tangential accn.. this accn. acts tangentially to the path.

Angular accn is

centipetal accn :_ v^2/r

HOPe it helps.......

radial and centripetal acceleration are same which acts towards center resulting circular motion It there even if the object is moving in circular path in constant speed. this arises due change in direction of the velocity , velocity is vector quantity so we can change it by changing it direction as well as magnitude .

Angular and tangential acceleration are same but one is angular variable and the other is linear . which comes in to play due to the changing magnitude or increasing or decreasing speed of an object moving in circular path note here that centripetal is present here as well since the object is moving in circular path . here the net acceleration of the object is the vector sum of tangential and radial acceleration which stays normal to each other ( generally )
