What is Newton's Third Law of Motion?

• an object at rest stays at rest, and an object in motion will stay in motion until an outside force acts upon it

• the acceleration of an object will be equal to the net force of an object divided by its mass

• an object that is not moving will stay not moving moving until an unbalanced force acts on it

• for every action, there will be an equal and opposite reaction
