Rod,

As long as you continue to accept energy is transferred between bodies you will continue to base all your argument on a gross misunderstanding of physics. I don't know where you got your book and practical application of physics; I got mine while obtaining an engineering degree and am licensed in six states as a Professional Engineer. The point is you are wrong and with your mindset while never accept this fact regardless of what anyone says.

Please bear in mind the energy has been used for decades as a way to sell newer cartridges. Pondoro Taylor stated this in "African Game and Cartridges". Momentum just doesn't sound as exotic I guess.
