What makes some one knock out after a punch
when you get punched your brain hits thr back of your skull if pubched hard enough you will get knocked out.
When punched with enough force your head will stop moving but your brain will keep rattling along the walls of your head which will cause a person to be knocked out. This also causes concussion.
It is the pressure and location of the hit. If you're hit in the jaw with only 6.5 lbs of pressure, you're out cold. I am unsure of the specific mechanics of the weakness of the jaw, but i have been knocked out several times, not fun.
When you get hit your brain hits on back of your scull and it turns off for few seconds
The most common cause is when you are hit square on the side of the jaw. It sends a shock wave through the nerves and it's too much for the brain to handle so quickly.
