A person is hurt on kicking a stone due to – (1) Inertia (2) Velocity (3) Reaction (4) Momentum
by

1 Answer

Answer :

(3) Reaction Explanation: Newton's third law states that "For every action, there is an equal and opposite reaction." The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. So harder the stone is kicked, the harder will be its effect on the hitter.
