gravitational potential energy
... As the bob swings upwards it slows down. Its kinetic energy decreases as work is done against its weight. As it gains height the gravitational potential energy increases again. At the very top of its swing it stops for a moment. It once again has no kinetic energy, but its gravitational potential en ...
