Actually TS, I got that definition here:

I was reading some article a while back (yesm, grunts read too) about the amount of joules certain armor can withstand. I forgot about it. Then recently bought a book, a biography about Maj. Boyd (inventor OODA). The book sort of inspired me to look into the science of things, as he did.
So, had some free time, and thought I'd compare the amount of joules a given weapon produces, using different bullets. In this case an AK 105 with a 12 inch barrel. I compared 7.62, and 5.56 fired from the same weapon, using the muzzle velocity info from charts by Kalishnikov.
I thought I had determined that it would be much more devastating to be shot with the 7.62 than the 5.56 at point blank range. But I will now have to go and do the math over, double check definitions of joules.

Back to the drawing board.
Kinetic energy does not equate to energy transferred to the target, nor does it account for the wounding mechanism of the projectile's contruction.
In theory, a 6.8 oz. softball (193 grams) hitting you at 10 meters/second should damage you more than a 1 oz. icepick (28 grams) stabbing you at the same speed, but I doubt it.
This is far too complicated a topic to do justice to here, but suffice it to say that theoretical physics and terminal ballistics frequently contradict one another and are not likely to be reconciled by a layman.
