#mechanical_energy  energy in a mechanical form
  supertype:  #energy  (physics) the capacity of a physical system to do work; the units of energy are joules or ergs; "energy can take a wide variety of forms"
  subtype:  #kinetic_energy__kineticenergy__K.E.  the mechanical energy that a body has by virtue of its motion
  subtype:  #potential_energy__potentialenergy__P.E.  the mechanical energy that a body has by virtue of its position; stored energy
     subtype:  #elastic_energy__elasticenergy__elastic_potential_energy__elasticpotentialenergy  potential energy that is stored when a body is deformed (as in a coiled spring)
