+**Mechanical energy** is the sum of an object's [kinetic energy](/wiki/kinetic_energy) (energy of motion) and its [potential energy](/wiki/potential_energy) (energy of position). It is the energy associated with the motion and position of an object, enabling it to do work. This fundamental concept underpins much of classical physics.
