According to the principle of conservation of momentum, the total momentum of an isolated system remains constant before and after any interaction. In this case, when we throw a heavy ball while standing on a skateboard, we and the ball both have momentum in opposite directions. When we release the ball, it moves in one direction, exerting an equal and opposite force on us, causing us to move in the opposite direction. This is the recoil we feel. However, if we hold onto the ball and don't release it, the net momentum change in the system is zero since the initial momentum in one direction is balanced by the opposite momentum of the same magnitude in the other direction. Therefore, the net recoil will be zero.
