RG133002	The gravitational potential energy of a system containing a planet and a moon would be greater after the distance between the moon and planet increases..
RG167002	Stretching a rubber band increases the amount of elastic potential energy because the distance between the molecules that make up the rubber band increases, and intermolecular forces act to restore the molecules to the unstretched distance.
