Answer:
Reaction force
Explanation:
According to Newton's third law of motion, for every action, there is an equal opposite reaction.
Hence the reaction force is often equal in magnitude to the applied force but acts in a direction opposite to the direction of the applied force.
Hence, when a baseball player, gets a hit, the ball exerts a reaction force on the player which is equal in magnitude to the force with which the player hits the ball but opposite in direction.
