Not sure why you're replying to me. I literally referred to kinetic energy ("the energy expended to accelerate it") in my comment.

Your comment seems to be confusing momentum (m * v) and kinetic energy (m * v * v).

I'm not confusing anything, but I wasn't trying to be scientifially rigorous, either. By "energy of the momentum" I was referring, admittedly imprecisely, to the fact that the kinetic energy is a function of the momentum. Or, to be precise, E_k=p^2/2m. At least as I understand it.
