How does head butting someone in the head with your own head ever work

1.25K viewsOtherPhysics

I see this shit in movies all the time and it always just looks insane to me. Even just basic physics should mean that the equal and opposite reaction of one skull banging into the other would knock each person out equally. How does this ever work? The character always walks away like some badass as if they wouldn’t have some major concussion and are invincible. The only use of this I ever appreciated was the parody in an Adam Sandler movie where the guy did it and did actually pass out from it.

So I got assaulted by a dude much larger than me once. I was holding my own, when this fucker grabbed my arms, I couldn’t move. So I cocked my head back, and threw my forehead right into his mouth. That ended it.

The point is that you hit them in the *worst* part of their head with the *best* part of your head and, ideally, you’re braced for it while they aren’t.

Gently (*gently*!) hit yourself in the forehead, then the nose, then the forehead. Big difference, right? Now imagine your nose got hit full-force with someone else’s forehead, and you didn’t see it coming. They get the follow-through, you get a bit of whiplash, and they’re probably swinging before you can really react to it.

The point isn’t to go cranium to cranium with someone. Because that just sucks for everyone. A proper headbutt when used correctly it supposed to break the opponents nose you can think of it as a 7+kg hammer to the nose).

Not all parts of the head are created equal and you are in control of the impact. You choose a hard spot from your own head and, ideally, a soft one on theirs.

Bone of your forehead very hard and thick.

Bone of their nose bridge/zygomatic arch/maxilla comparatively soft.

It’ll still hurt you, and still might concuss you (the technically term would be a coup-contra-coup injury), but if you break their face, they’ll either be in so much pain they may be unable to fight, or, they literally might not be able to fight from lose of vision/inability to breath properly.
