... Newton’s first law is also known as the law of inertia. Inertia means the body wants to keep its present motion, whether at rest or not. If a body is moving at constant velocity, it wants to remain moving at constant velocity. If at rest, it wants to remain at rest. It keeps its inertia unless a net ...
