Newton's Third Law of Motion

Definition

Newton's Third Law states that for every action, there is an equal and opposite reaction. When one object exerts a force on another object, the second object exerts an equal but opposite force on the first object.

Analogy

Imagine two people standing on skateboards facing each other. When one person pushes the other, they both move backward due to the equal and opposite forces.

Related terms

Force: A push or pull that can cause an object to accelerate.

Action-Reaction Pair: The pair of forces that two objects exert on each other as a result of their interaction.

Equilibrium: A state in which all forces acting on an object are balanced, resulting in no net force and no acceleration.
