... Lesson 2. Newton’s Three Laws of Motion Newton’s Three Laws of Motion 1st Law (The law of inertia) – An object will continue in its state of rest or constant velocity (both magnitude and direction) unless acted on by a NET force. The NET Force is defined as the Sum of all the force vectors acting ...
