I often see people writing about "transfer"of kinetic energy but no one seems to want to quantify it.
Which seems odd for such an easy-to-quantify commodity.
How much energy must be "transferred" for the bullet to be effective?
I wont quantify precisely how much , but I know for fact that less energy transfer can prove more effective.
ie; a solid that does the work/task required of it and exits ,vs, a soft with the same energy on impact
that then fails to do the work/task required, but still spends all its energy coming to a stop in the animal.
