... NEWTON’S FIRST LAW: Consider an object on which no net force acts. If the body is at rest, it will remain at rest. If the body is moving with constant velocity it will continue to do so. Note that forces may still act on the object but the net (resultant) must be zero. Newton’s first law is sometime ...
