What are Newton's three laws of motion?

1. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force. 2. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. 3. For every action, there is an equal and opposite reaction.
