Newton's laws of motion - Wikipedia
https://en.wikipedia.org/wiki/Newton's_laws_of_motionNewton's first law, also called the "law of inertia", states that an object at rest remains at rest, and an object that is moving will continue to move straight and with constant velocity, if and only if there is no net force acting on that object. If any number of different external forces are being applied to an object, then the net force is the vector sum of those forces, so . If that net force is zero, then the object's velocity must not be cha…
Newton's laws of motion - Wikipedia
en.wikipedia.org › wiki › Newton&Newton's laws of motion are three laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: Law 1. A body continues in its state of rest, or in uniform motion in a straight line, unless acted upon by a force. Law 2.
