Review and expand the theory of gravitational potential energy (GPE) being due to the force needed to lift an object against the force of gravity a certain height. Work is done to lift the object, the more work done the greater the distance raised and the greater the GPE. Release of the object from the height will cause the GPE to convert to kinetic energy (KE). Charged objects have an electric field which travels out from the charged object in all directions. A second, smaller charged object will have potential energy (PE) by virtue of its position in an electric field. To move the smaller object closer to the larger charge of the same type, a force must be applied and work done to push it against the electric field. The electrical potential energy (EPE) is increased when work is done to move the charge against an electric field. The PE/ charge is the electric potential which is measured in units called volts.
