But motion IS heat! Heat IS "the vibration of molecules and atoms!" ALL energy eventually dissipates as waste background heat, though it can go through a number of other forms first. Why we can't have perpetual motion machines: when energy changes form, some always becomes heat -- can't change form for free. #DisapointingThingsLearnedFromMyFather
