Mechanical Energy is the energy that an object has due to is motion or position, this can be either kinetic energy or potential energy. Non Mechanical Energy on the other hand is energy that does not fall into the category of energy from position or movement.
Mechanical energy describes the ability of an object to do work. The work done on an object arises from a force applied over a distance (W=Fdd) which either accelerates the object thus changing its motional energy (kinetic energy), or stores energy by changing its position (potential energy).
