For instance in an elastic collision of two indivisible particles...
Why does [itex]m v^{2}[/itex] stay constant? Why not [itex]m v^{3}[/itex]?
[That is, where other type of energy are unavailable (potential, electrical, mass, etc.)]
In other words, why does the physical unit: [itex]kg \cdot m^{2} / s^{2} [/itex], or Joule, stay constant?
Please keep the discussion in classical terms...
