Definition : The measure a body’s ability to do work.

Energy is the amount that is done by a body, that is the amount of force that it took to displace it times the displacement. Energy, like work is measured in Joules. Energy cannot be created an destroyed, it can only be converted from a dormant potential energy to the active kinetic energy. Thus total energy of a body is equal to potential energy plus kinetic energy.
