kicked ball?

[drmarcus]

If a player unintentionally hits the ball with his leg or foot, is that a kicked ball violation? If A1 throws a pass and it hits off B1's leg or foot while B1's foot is on the floor and B1 has made no effort to stop the ball with his leg or foot, that is not a violation, as I understand it. But what if its the same situation, but B1 has jumped (but has still not purposefully moved his leg to hit the ball)?

What if there is a loose ball and A1 in making a normal running motion, and making no intentional effort to hit the ball with his leg, strikes the ball with his shin or knee, is that a violation?

What if A1 throws a pass to A2 and the pass hits A2's foot or leg before any other part of the body, is that a violation?

Thanks in advance.
