Physics Of Firearms
From the viewpoint of physics (dynamics, to be exact), a firearm, as for most weapons, is a system for delivering maximum destructive energy to the target with minimum delivery of energy on the shooter. The momentum delivered to the target however cannot be any more than that (due to recoil) on the shooter. This is because the momentum imparted to the bullet is equal to that imparted to the gun-shooter system.

Famous quotes containing the word physics:
“Although philosophers generally believe in laws and deny causes, explanatory practice in physics is just the reverse.”
