Maxwell s wheel momentum demonstration apparatus rvfm ph10562 p maxwell s wheel apparatus demonstrates momentum conservation of energy and torque it consists of a large flywheel suspended by two strong cords the cords are wound around the shaft of the wheel and then released p p the wheel unwinds the cords as it falls and winds itself back up as momentum continues to spin the wheel this process will continue for several oscillations gradually coming to a stop as the wheel loses mome
