Is the reason we don't have any perpetual motion machines because of the first law of thermodynamics? Would it be possible to create one if there was a wheel, and it had a push– if it was frictionless, and in a vacuum, would it spin forever? Also, would gravity matter if friction wasn't in the equation?
