Physics 231 Topic 3: Forces & Laws of Motion
... If it was moving with a certain velocity, it will keep on moving with the same velocity. Second Law: The acceleration of an object is proportional to the net force acting on it, and inversely proportional to its mass: F=ma Third Law: If two objects interact, the force exerted by the first object on ...
