only by wild
speculation. The mechanical potential function only enables
one to define
a scalar constant of the motion, and to represent certain
forces as the

gives no hint of
the universal FLT - this is rooted in speculation and the

of experiments (Joule).

In a closed system, are there any "energies" that are not either
kinetic (either microscopic or macroscopic) in nature or potential
in nature?
