Newton's First Law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity, unless acted upon by a net external force. This means that without any force acting on it, an object's state of motion will not change. Inertia is the tendency of objects to resist changes in their state of motion. This law highlights the concept that forces are necessary to change an object's velocity (either to start moving, stop moving, or change direction).
