Electric potential energy, or electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.or example, an electron would have a negative value of charge when placed in the formula). The following outline of proof states the derivation from the definition of electric potential energy and Coulomb's law to this formula.
1 Electrical Energy is when electricity creates motion, light or heat. 2  An example of electrical energy is the electric coils on your stove. 3  Gravitational Energy is motion that is caused by gravity. 4  An example of gravitational energy is water flowing down a waterfall.
