You often see action scenes in media, where a person is thrown so hard against a concrete wall, it breaks.
My question is if it's possible for a softer material to be accelerated to point where it would penetrate a harder material to a substantial amount. Does velocity even play a role in this? (Guns?) Or is it all material structure or hardness?
I guess I want to know which forces play a role at any given impact and what happens to both objects. Or does it all come down to material structure, flexibility and brittleness? I am really sorry if this is all over the place, I lack the physics education to phrase my question correctly.
