Click check box to show the angular velocity with respect to the ball,,or the velocity at the bottom of the ball relative to the table (Vx-R*omega: friction force will be in the opposite direction).
You can have backspin or topsion by draging the slider to change the ratio R*w/vx (negative value for backspin).
