Does a body appear stationary in Center Of Mass frame? I am aware of the fact that a system is at rest in COM frame and its net momentum is zero, then is the net angular moment zero too and does the body appear in rotation in the COM frame or does it appear completely stationary.
Let's say C is the centre of mass of a cylinder with radius $r$ and A is any arbitrary point and the body has a translational constant velocity $v_0$ and is also rotating about an axis perpendicular to the plane of motion and passing through COM . Now in the frame of COM its clear that $v_0$ needn't be considered but what about the rotational velocity. Let's say I want to find the acceleration of point A. Is it $v_0^2/R$ in the direction of C as centripetal acceleration or is it the same in the opposite direction as a pseudo acceleration?
