potential energy: potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
work done: Work done by a force. Work is done whenever a force moves something over a distance. You can calculate the energy transferred, or work done, by multiplying the force by the distance moved in the direction of the force.
power: The ability or capacity to do something or act in a particular waypower is the rate of doing work or transferring heat, the amount of energytransferred or converted per unit time. Having no direction, it is a scalar quantity. In the International System of Units, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the condenser steam engine. Another common and traditional measure is horsepower
