I am wondering something, what happens to kinetic energy, say from a bullet hitting a metal plate, does it convert into something else (i.e. heat) or does it just stop?

Ah, okay. Yeah, if the bonds are strong but elastic, then the bullet will bounce a bit, and the difference of the initial and final velocities of the bullet (it will be bigger, since the final should be negative) gives you the amount the person feels. It'll be felt more at the epicenter of the collision, though, since the elasticity means it will be temporarily deformed.Scribbles said:Kimura said:When is that? >.>Yangfan said:Don't forget the case where the bullet bounces back.![]()
I think its when the bonds are stronger and the material is elastic.
