No, quite the opposite. The statement you made is the one that Aristotle made. Galileo made the claim (and it is borne out) that the OPPOSITE happens. That things in motion do NOT come to rest in their natural/ original position, but continue to move *forever*, unless acted on by an external force. Aristotle was proven wrong. The statement that objects in motion tend to arrive at their natural/original position on their own is WRONG. > > Newton's laws of motions: > First law: "Every body persists in its state of being at rest or of > moving uniformly straight forward, except insofar as it is compelled > to change its state by force impressed" You see?

A mass in motion does have momentum, but that is not the only example of something with momentum. It's a little like defining mammals as critters with fur and four legs. It is true that critters with fur and four legs are mammals, but those aren't the only mammals. > 2 > Mr PD will you stop once and for all with your > fucken demagogic patronizing = Freshman ??!! > > my definition is a bit more basic than yours And it's wrong. Moreover, momentum is not a cause. Momentum is a conserved quantity. The interactions that exchange momentum can be considered causes. > > do you waht to get from me > your 'freshman' backwards as an reaction (:-) > > Y.Porat > -------------------------
