Action and Reaction Third Law of Motion - Equal and Opposite Forces Whenever one object exerts a force on a second object, the second object exerts a force of equal value and opposite direction on the first. This has one very important implication - forces ALWAYS occur in pairs; the action force and the reaction force If one of the forces is designated as an action and the other force is designated at the reaction then Newton’s Third Law can be restated in this common form. “For every action, there is an equal and opposite reaction.” Understanding the Third law • In each case, a pair of forces are present. Each action force is matched by a reaction force. • Recall, we stated earlier that if two equal and opposite vector forces are applied to an object, they would cancel each other out and the object would remain at rest. • How do we reconcile this
