Universal Gravitation
... It may seem reasonable to think that if weight = mg, since weight = 0, g = 0, but this is NOT true. If you stand on a scale in an elevator and then the cables are cut, you will also weigh nothing (ma = N – mg, but in free-fall a = g, so the normal force N = 0). This does not mean g = 0!
