Qualitative Power

if you hit something tthat something moves with the punch, if your punch is slow and forcefull all your doing is pushing the object away with a slight impact before the push, if your punch is fast with a little force you have a great impact with a little push right after the impact.

this breaks down to work/displacement = force of impact. thus 2 people can have the same work but due to their velocity the displacement is different causing a much different force of impact.

there is also a diffrent equation that uses the duration of impact instead of displacement to clculate the force of impact resulting in the longer the impact takes the lower the force of impact is and the shorter the greater the impact is.....but i didnt really spend much time looking into that.


as well how the punch is throw dosnt matter. thats a diffrent equation where your body does work to your arm. while the impact of a punch is where you fist does work to your opponents face so all you need to know is mass behnd the punch and its velocity right before impact, how much the object is displaced at impact, and the finaly mass and final velocity after the work is done.

 

you would have to use it in a controlled environment like on a punching bag and have it recorded in slow motion to get the actual value but one could put in hypothetical values and infer from the out comes.

 

im not sure what you disagree with but i agree that there is alot more to it in reality like techinique has alot to dow ith how much weight is behind some ones punch just as distance has alot to do with the final velocity of the punch so simply having better punching technique or a better sense of distance can vastly improve your impact force and in reallity it would be really hard to figure those things out.....even more so id imagine that diffrent segments of the mass behind the punch are going to be moving at diffrent speeds like the mass of your back isnt moving as fast as the mass of your arm. and all that dosnt even factor in whether your opponets moving twords you or away or off balanced or any of that stuff.

so really tghe functionality of such equations to real world situations is minimal but you can still infer that mass is no where near as important as velocity of an impactt, like hold a piece of paper with one hand and try to punch though it, the paper moves out of the wya and you barely have any impact, now try and flick the paper, you might not go through the paper but you defianly have a better impact with just one finger then when you tried to punch though it with your whole fist.

 

I was just joking bro, i struggle with times tables. No idea at all what your math post was about

 

oh, well all that math stuffs probly wrong any ways so it dosnt really matter.

 

I agree with this. There certainly is a few different types of power punchers and you can easily name fighters who delivered power in the ways you mentioned.

 

? I tend to agree...

 

Really?

I cant work out how distance could have anything to do with the force of the blow, as he says. Although i suppose it does stand to reason

He is saying the Ke/ Distance = Force of the blow. This means that the way to increase the force is to reduce the distance it is thrown from. Meaning that the bigger fighters such as todays Superheavyweights will have less force because they travel a greater distance. Meaning that Someone like Bob Fitzsimmons would probably be the greatest KO puncher ever! Although i must say that Rocky Marciano would also be underated on this theory also.

I guess that this is yet another reason why Fitzy astounds everyone. Even based on modern mathematical theory, he is going to be the biggest hitter :think

 

no

its the distance of deceleration a better term would be displacement of the object.

how the punch is throw really doesnt come into the equation. its just the duration of right before impact and right after.

like f=ma isnt your mass or your acceleration its the accleration and mass of the object your hitting. like if you hit your heavy bag and recorded its acceleration and knew its weight you could calcualte the force you put into it that force*the displacement of the object = work. but as f=ma only has to do with the object your hitting you really cant infer anything from it as well thats how accelerometers work they just measure your acceleration and give your impact force.

so since force*displacement = work and work = the change in kenetic energy

so with kinetic energy it is how fast your punch is right before impact and the mass behind the impact i think so you calculate the change in kenetic energy which is complete change going from full force to stopped so essentially kinetic energy is the work thus

w=f*displacement

so you sovle the equation for f=w/displacement to calcualte the force.

 

So when Fitz hit 260 lb and he fell at 9.8m per second (round up to 10), he was hitting with 2600 psi? :think

Sounds a lot more than the modern super heavies are recorded at!

 

There's no simple (or not so simple) formula as to why some guys hit and others don't.
I mean, that's like expecting there to be a simple formula that will explain why one racing car has better performance that the next .... it's all in the details of the design and how the various components work together, not to mention the human element.

Anyway, the distinction needs to be made between :

1. punching force or 'raw power'

AND

2. actual applied punching POWER

(1) can be based on strength, mass, speed, delivery technique, muscle fibre, whatever. You might even be able to measure it on static targets, pounds-per-square-inch. Somewhere someone might work all that out all the relevant biomechanics of it as file a load of formulae on it.

(2) is, in basic terms, KNOCKING MOTHER****ERS THE HELL OUT (with a punch or a few). That's real power.
And it's a skill or an ability. It's a deed.
Timing may be the most important factor. Precision likely is too.

 

Hearns?

 

no if fitz hit an 8 lb head and at that very very fist instant of movement his opponet head accelerated at 9.8 meters per second per second you would have to re compute the whole thing so the out come would be in newtons then convert that to psi how ever. the weight of the body dosnt necessiarly have much to do with the knock out as the impacts goal is to accelerate the head so quickly that the brain smashes into the side of the head.....or you hit the button and drive the jaw into that nerve.

but really none of that matters because the 9.8 meters persecond is gravity and you have no idea how fast his opponents head accelerated so you have no idea how hard he hit.

unless you have actual reality based numbers that you recorded and measured the only thing you can do with the equations is put in hypothetical numbers and infer from the out comes.
