What are Newton's 3 laws of motion?
Law 1: a body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force
Law 2: the force acting on an object is equal to the mass of that object times its acceleration F = ma
Law 3: For every action, there is an equal and opposite reaction
