The tangential acceleration is a

_{T}=r*α where α=1/2*(ω

_{f}-ω

_{0}). So we can see tha a

_{T}is dependant on both the initial angular velocity ω

_{0}and the final ω

_{f}).

For centripetal acceleration, we instead have a

_{C}=r*ω

_{f}

^{2}.

My question is, how come the centripetal acceleration is only dependant on the final angular velocity, and not the initial?

Is there a physical explanation for this?
