Third Law of Motion

Whenever two bodies interact, they exert force on each other. One of them is called action and the other is called reaction. Thus, forces always exist in pairs.

Third Law of Motion

Third law of motion states that to every action, there is an equal and opposite reaction.

When two objects interact, the force exerted by one object on the other is equal in magnitude and opposite in direction to the force exerted by the latter object on the former.
