    Undergrad Is Perpetual Motion by Gravity Possible?

    no perpetual motion possible even with gravity all have a start and a end.you can create motion but will stop eventualy.on Earth if you use gravity and weight to make motion you need the same force to pull up so it even think to a stop motion sorry...
