Rather academic, but informative

 I love this quote:  Energy is the messenger, momentum is the message.  



It also helps explain why the 45 ACP is still so popular a cartridge.  Yes, it's slow.  But it's also heavy, which means that the power expressed on the target is much more than the 9mm.  Don't get me wrong, I enjoy both calibers, but for different reasons.  

When it all boils down, energy=massXvelocity.  Physics never lies.
