classical mechanics and much of modern physics. His first law says that an object at rest will stay at rest, and an object in motion will stay in motion, unless an external force acts on it. This quality is called inertia. His second law states that the force exerted by an object is equal to its mass times its acceleration. His third law states that every action has an equal and opposite reaction. In other words when you push an object away, an equal force pushes you away from the object. Newton proved all of these principles, or laws, mathematically, and while they do break down in certain situations, they apply to almost everything you experience in everyday life.
