Wally Perrien: KE= energy of an object that's in motionPE= energy within an object because of gravity... it has the potential to become KE if it fallsConservation of p = an isolated system (no outside forces acting on it) will not loose or gain momentum conservation law = an isolated system does not loose or gain energy... or anything, for that matter (nothing outside it forces it to) it can change, but only because of internal actions (meaning that stuff going on inside it is causing it to change)this question should be under physics, not conservation....Show more
