4.3 Newton`s Second Law of Motion
... of Motion Newton’s first law is called the law of inertia: In the absence of an unbalanced applied force (Fnet = 0), a body at rest remains at rest, and a body already in motion remains in motion with a constant velocity (constant speed and direction). The bottom line: There is NO ACCELERATION in th ...
