Is Quantum Mechanics Incompatible with Newton`s First Law of
... Newton’s first law is a special case of his second law since the absence of a force leaves the body in its original state of uniform motion. We shall see that Newton’s second law can be derived from Schrödinger’s equation, which was set up to yield Newton’s laws of motion in the classical limit. So ...
