The reaction force to the action of a person pushing on a ball when throwing it is the ball pushing back on the person. This concept is explained by Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. Understanding this helps us grasp the basic principles of forces in motion. ;
