Newton's Third Law of Motion
Newton's third law of motion states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object. Another way to state the third law of motion is that for every action there is an equal but opposite reaction.
Action-Reaction Pairs
Pairs of action and reaction forces are all around you. For example, when you walk, you push backward on the ground with your feet. Think of this as an action force. The ground pushes forward on your feet with an equal and opposite force (this is the reaction force). Action and reaction forces don't cancel out each other because they act on different objects.
