WebBy using the two different forms of the equation for the magnitude of centripetal acceleration, a c = v 2 / r and a c = r ω 2, we get two expressions involving the magnitude of the centripetal force F c. The first expression is in terms of tangential speed, the second is in terms of angular speed: F c = m v 2 r and F c = m r ω 2 .
