What is Newton's Third Law of Motion?

• For every action force, there is an equal and opposite reaction force

• An object at rest will stay at rest, and an object in motion will stay in motion

• The acceleration of an object is directly proportional to the net force applied to it

• The force of gravity between two objects is directly proportional to their masses
