    Graduate Momentum vs. KE - which determines projectile penetration?

    Poncelet developed equations to explain this. I played around with it and found some interesting insight. Ek is mv^2, while momentum is mv^1. Poncelet penetration in bone is proportional to mv^2, while in flesh mv^1.2 ! This is due to the the respective friction experienced, that the importance...
