I don't get it. How can a punch like this knock someone out? https://www.youtube.com/watch?v=P7ZMMyDNUVU
thing is to knock someones lights off all you need is speed and accuracy. you see those fuckhuge haymakers online a lot, but i took quiet a lot of them and they didn't do shit. you don't really need your body-weight behind a punch for it to hurt. but it sure easier to fuck up your hands if you do.
former boxer here btw.
well it's all about the rotational acceleration you give to the skull, jaw is just a lever, altho a very powerful blow can dislodge the jaw and possibly push it into the carotid artery (instant lights out).
either a fast light punch or a slow heavy punch will do, for this reason. altho speed is the more important factor in physics.
>how can a punch like this knock someone out
>video of a pretty solid punch
He stepped into it, followed through, and caught him right on the button..
what more do you want out of a punch?
Yea he's definitely thrown a few punches before. Not like he even really needed any experience to get a good shot in on that goofy ass crouching tiger guard though.
I thought that black dude was gunna pull out some Jackie Chan shit for a second lol.
Shut the fuck up kid. Quit spouting your common sense bullshit like you're some kind of expert.
Sick of people like you that get on an ANONYMOUS image board looking for recognition.
>speed is the more important factor in physics
You couldn't have something dumber than that if you tried. Speed means nothing. A quick jab with no weight behind it isn't going to knock someone out just because it's fast. If you had even the slightest boxing training, you'd have learned to put your weight into every punch. And if you had even the slightest knowledge of physics, you'd know that force=mass*acceleration.
>inb4 B-BUT I SAID SPEED
Acceleration is not the same as speed.
Meh that kind of fighting takes years of training for a reason. There are definitely some crazy spin kicking hidden dragon motherfuckers out there, but they would have been well out of reach by the time that punch came in.
I think that guy was either drunk or was just trying to bluff and throw the whiteboy off his game for a second.
Hell, maybe he left himself open like that on purpose hoping to make the white dude take an obvious swing so he could fuck him up when he missed. He underestimated him/overestimated his own speed if that's the case though..
>energy = speed^2 * mass
I think the equation you're looking for is energy=mass*C^2(The speed of light squared)
Which is an equation explaining the amount of energy something has in relation to it's speed and mass. It has literally nothing to do with punching.
it has your hand has mass and speed and energy, the energy is transferred to the guys face as your fist decelerates and his head accelerates.
don't think i can explain it in simpler terms.
Thanks for the info guys. It's just I've always wondered what it would take to land a punch like that.
Enjoy, although I don't think she made any other nude gifs.
A punch with 0 weight and 0 energy behind it wouldn't even be a punch you fucking spaz.
Well, you just confirmed that you know literally nothing about physics.
Accelerating is just changing direction or velocity, slowing down is accelerating, turning is accelerating. You're just making it worse son, stop while you're ahead.
e=mc^2 relates to the potential energy of matter. The amount of pure energy something will produce if completely obliterated. (IE:Anti-matter coming into contact with it's matter counterpart.)
Just... stop. You're embarrassing yourself.
he said "every punch has weight behind it" i just agreed.
thing is what i found during my boxing carrier is the difference between a well executed punch being a knockout punch or just a dazing one is putting your shoulder in it (or as some calls it punching thru). everything else is the same motion starts from the legs builds up through your hips and torso rotation and shoulder and arm and extend and rotate fist, it's like a flow of momentum or more like a wave that gets stronger as it progresses i don't know. but if you don't turn your entire shoulder into it it's a sparring punch, if you do it's a lights out punch. you center of mass should not move with your punch that is what peasants do.
Peeple think you can take as many hits in the face as in the action movies you cant and i think he got him right in the throat thats instent ko almost most fighter will bend their head alittle forward to cover neck better
sure, i will allow that speed is a vector, and acceleration is a matter of perspective and physics don't know about any deceleration just as it can't do shit with cold or such, sorry for using common language.
Backpedaling so hard, this is delicious.
If you're going to try and bring physics in to explain your fuckups, at least know what the fuck you're talking about.
Energy is not the same as force.
I assumed you knew the terminology when you started spouting off bullshit.
You're either underage or retarded, either way, fuck off.
I should pay better attention to id's. Didn't realize you were the /b/oxerbro lol.
No real training here but I've got four older brothers, so I know damn well what a good punch feels like. I've taken enough jabs to the fucking nose/solar plexus/jaw/kidneys/you name it to know that a weak punch can be just as effective too.
I'd rather take constant haymakers to the cheeks from a dude twice my size than fight someone half my size that knows where to hit me..
i got punched in the face a million times...
ko-d 0 times. almost ko-d 1 time it was a fast light tap to the chin legs got all wobbly and shit.
just saying don't think in simple terms off numbers, cause once you have kinetic energy down shit gets awfully complicated by bio-mechanics and technique.
I'm pretty sure it depends where you're hit. I've been straight walloped in the face during actual fights and it didn't even hurt until after the fight was over. Then I've also been kicked in the side of the head during Tae Kwon Do matches with not even that much force with them wearing padded footguards, black outed and next thing I come back to is me laying on the ground trying to figure out how that happened. I think I've heard it has to do with a certain nerve in your face or something.
Am I the only one who's fucking anoyed at that stupid bitch for punching the guy on the ground? Bitch this is why you get rape. Mind your own fucking business. You stupid cunt. Bet this all started because she was yapping her stupid mouth in the first place.
It is not Nyanners, she is much shorter.
I have seen her full videos somewhere and she does a striptease to the jungle book music with a feather boa in the very same room and camera angle the gif is taken
Ok guys, I found the real source.
>>559886343 was right. Here's a link to live cam:
Holy shit, this preschool physics.
The total amount of energy in your punch means fucking nothing kid.
It doesn't matter how much force you connect with, all that matters is where the hit connects and if they're ready for it.
You pretty much just need to get their head to move enough for their brain to hit against the inside of their skull. Physics has nothing to do with this shit, just stop bringing it up.
If someone is ready for the punch, their neck is going to absorb the impact and their head will stay stationary.
>hurr u don no how 2 fite cuz u calledd out his horrible physics
My record in silver gloves was 18-4-2 with 4ko's at 14. Mostly won because I was a 6 foot featherweight at the time and had reach on literally everyone, but I understand how to knock someone out better than the retards spouting off common sense bullshit.
if you were here, and we had a pair of gloves we could short it out gentleman style. but i'm not gonna travel to an other continent for you education.
tldr physics has everything to do with how you make someones brain move around his skull imho. also if i get you in the chin your head will not remain stationary even if i just go half steam.
if have really boxed you should know that it makes a world of difference where and from what direction you receive the hit. what slides harmlessly off your tiny chimp skull will seriously rattle you if it comes sideways to the tip of you jaw.
and that is cause physics and shit.
getting knocked out by a blow to the head happens due to mechanical deformation of neurons in your brain, which (as far as we know) results in them firing when they shouldn't, and causing something similar to an epileptic seizuere
the brain is jelly-like in its consistency and it's quite easy to cause forces in a site far from the blow; all depends on where the the head was hit and how hard
An accurate mathematical model of a KO punch would have such a ridiculous amount of variables that it's completely unfeasible.
It's not just
>This amount of force to their head results in a knockout
It would involve a ton of differential geometry with constantly changing resistances and fulcrums.
It's also not just the velocity of the punch, it's the relative velocity to the person being punched.
Good luck trying to represent a KO punch with actual math.
it'd be fairly trivial to simulate the brain recieving a punch using a FEA model (especially if you used brain scan data for the geometry), but you'd also need to account for stuff like the fact that grey and white matter have different densities, and that for moderate to severe traumatic brain injuries, the injury tends to happen at the interface of the grey and white matter because of axons being stretched, sometimes to the point of shearing
that and a bunch of other stuff would need to be known about the electrical and chemical functioning of the brain
>An accurate mathematical model of a KO punch would have such a ridiculous amount of variables that it's completely unfeasible.
well that is at least true, but... if you don't have the kinetic energy, the rest is shit. the total energy of your fist and arm is what the maximum ko potential you have.
then it's the other guys turn to decrease it with his deforming facial bones, the angling of his skull, etc... and then your hands will take some of the punishment too, depending on your technique and equipment.
<What the fuck?
well op, the jaw is incredibly sensitive, where it connects to the skull (about at the bottom of the ear) is more or less directly connected to the conscious center of the brain (science just learned where this place was). boxers, American football players, and other full contact sports players wear mouth guards in order to space the jaw so it's less vulnerable, but when your teeth hit together really hard it also collapses the rear portion of the jaw sending a shock directly to the brain. resulting in concussions, hemorrhaging, and sometimes even knockout.
