Recoil occurs because one object exerts a force on another, and the equal and opposite force causes the recoil. In the case of throwing a heavy ball while standing on roller skates, the ball exerted a force on the person, causing them to move in the opposite direction (recoil). However, if the person goes through the motions of throwing the ball but holds onto it, there is no object for the person to exert a force on, and thus there is no equal and opposite force causing recoil. Therefore, the net recoil is zero.
