I already know sliding friction of ball on a flat table and rolling resistance of it.
How do I know coefficient of friction value when the ball has backspin with some angular velocity $\omega$? And also when it overspins (spinning faster than it would when rolling).
Also, we consider a ball with sidespin (spin around z axis), but with no spin around other axes sliding?
Also, does sidespin affect the coefficient of friction at all?
