I agree with the first half of this statement but not the second. Say I am in an inertial frame looking at you standing on a rotating platform at some distance from the rotation axis. I see you rotate and conclude that the force of static friction provides the centripetal acceleration needed to keep you going in a circle. As far as you are concerned, you are not rotating but you experience a centrifugal force which is canceled by the force of friction at your feet, so that you remain at rest in the non-inertial frame. As far as you are concerned, you are not accelerating and the centrifugal force you experience is not the cause of any rotation in your frame.NTesla said:My understanding is that: In an inertial frame, centripetal force is the cause of rotation, and when viewed from a non-inertial frame of reference, centrifugal force is the cause of rotation.
