1. In Current Science, energy is the ability to do work.
A fixed quantum of energy (~939.565 379 MeV, ~1.505 349 631 x 10-10 Joules) is one of five absolute properties of the two primal movement/energy forms spin and rise. When the two absolute movement/energy forms are linked, their combined absolute properties creates a fixed quantum of matter with a mass equal to ~1.674 929 351 x 10-27 kg, in the form of three elementary particles with an invariant topology and a fixed distribution (0.998,623u, 0.000,544u, 0.000,833u) of mass.
There are only five forms of de-linked movement/energy in nature, three from spin and two from rise. Each is a elementary form of nature. The five energies appear from the de-linkage of 0.000833u of neutron plasm spinrise matter [3a] with the little bang:
- [6+] positive electric charge shells – 0.5 x 0.000833u absolute (1st Law) spin movement/energy in a fixed volume shell surrounding the matter core [1b] (proton).
- [6-] negative electric charge shells – 0.5 x 0.000833u absolute (1st Law) spin movement/energy in a mirror split shell, equal in volume to the proton electric shell, surrounding the the inverted matter membrane [2b] (electron)
-  photons – radiation (free 2nd Law spin movement/energy bubbles carried by space at the accelerating speed of space) made from: a) nuclear radiation (gamma rays), from various nuclear interactions b) atomic radiation (x-rays – visible), from electric field interactions between electrons and nuclei c) thermal radiation (infrared – radio), from atomic and molecular vibrations.
-  zomons – space quanta – ~2/3u avg. absolute (1st Law) rise movement/energy pulses expanding and diffusing-in- place at the accelerating speed of absolute movement.
-  motion – kinetic energy – ~1/3u avg. (2nd Law) rise movement/energy bound to matter.
Each of the five forms of energy can be considered as belonging to one of two types:
- 1st law type energy, or intrinsically accelerating with time energy. The two fixed volume electric dipole charge shells and expanding & diffusing-in-place zomons are 1st law type energy.
- 2nd law type energy, or intrinsically non-accelerating energy with time. Photons of radiation and the kinetic energy carried by the momentum of matter are 2nd law type energy.
