NEWTONS LAWS OF MOTION #1 - An object at rest, stays at rest unless acted on by an outside force. An object in motion, stays in motion unless acted on by an outside force. #2 - The sum of the forces on an object is equal to that object’s mass multiplied by its acceleration. #3 - Every action has an equal and opposite reaction.
