May 26, 2014 at 22:41 comment added dmckee --- ex-moderator kitten A word on the place of "derivations" in physics: physics is not a branch of math and some things are accepted because that is the way thing are. We do derivations, because that is how we show that some allegedly fundamental inputs agree with observations and rules from a less fine-grained understanding; but the complex made up of the notion of energy, the work-energy theorem, the concept of momentum, the impulse-momentum theory, and the definitions of force and mass are in a real sense observationally founded. They can be checked for internal consistency, but they are what they are.

Adding a new question, in order to make my "central" question clearer.
