This suggests identifying rest mass energy with internal energy.
But that isn't really a clean third category, insofar as it
includes all of the hidden kinetic and potential energies of the
system. In turn, what is "hidden" depends on how closely you
are willing to look, ie. macroscopically (the whole system is
one object), mesoscopically (the system consists of a set of
blocks, springs, flywheels, planet, etc.), or microscopically
(molecules translating and rotating, atoms vibrating, and
maybe even electrons orbiting). Carl
