Forces of matter Newton's first law: the law of inertia • Inertia states that an object at rest will stay at rest until a force acts on it and an object in motion will stay in motion until a force acts on it. Newton's second law: The law of Acceleration • Newton's second law states that the acceleration of an object increases with increased force and decreased with increased mass. • The acceleration of a body is parallel and directly proportional to the net force F and inverse to the mass. The two people are pushing with the same power so they don't move. Newton's third law: action reaction law • Newton's third law states that for every action there is an equal and opposite reaction. • The mutual forces of action and reaction between two bodies are equal, opposite and collinear.
