Newton's 3rd Law Pair states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts a force of equal magnitude but in the opposite direction on the first object.
Force: A push or pull that can cause an object to accelerate.
Action-Reaction Forces: The pair of forces described by Newton's 3rd Law, where one force is the action and the other is its equal and opposite reaction.
Momentum: The product of an object's mass and velocity, which represents its motion and determines how difficult it is to stop.
