Four kinds of energy are:
1. Mechanical energy
2. Chemical energy
3. heat energy
4. Light energy
The four kinds of kinetic energy are mechanical,sound, electrical and thermal energy.
They are the four kinds of nucleotide bases.
The "two" kinds of energy are real and vector energy. Mot accounting for the two kinds of energy is the cause of current confusion in physics. Newton and Einstein missed the two kinds of energy real and vector. The gravitational energy is E= -mu/r + mcV. The first kind of energy Newton got the real or potential energy -mu/r. The unaccounted for energy is the "vector" energy mcV. The vector energy is the source of "dark energy" and myriad mysteries in cosmology. The Universe has two kinds of numbers, real numbers and vector numbers. This gives two kinds of energy, and two kinds of forces ,etc,etc,etc. Quaternions are the answer to the "two kinds" of energy, "reals and vectors" or quaternions!
