... momenergy

The word momenergy, a term first coined by J.A. Wheeler, refers to the single concept which ordinarily is referred to by the cumbersome word ``energy-momentum''. Given the fact that, in the physics of particles and fields, the concepts ``momentum'' and ``energy'' are merely different aspects united by a change of inertial frames into a new single concept, the case for correspondingly uniting the compound word `` momentum-energy'', or ``energy-momentum'' into the single word ``momenergy'' is appropriate.
