Suppose we have a rotating frictionless disk and there is a rotating observer on the center of it. Furthermore, suppose a very small ball on the disk's edge. Now we clearly know that the ball is not moving but the rotating observer sees the ball following a circular path with an angular velocity ω opposite of the one of his frame of reference. He now has to explain that movement and, since he is in a non-inertial frame, he has to introduce some non Newtonian forces. Accepting that the ball has a relative velocity vr in the non-inertial frame, the question is:
Is there a centifugal force and a Coriolis force acting on the ball? Or does the ball have to "physically" be included on the disk?
