Maybe I don't understand physics but size=power, right?

Speed + technique + timing = power

 

Jab is actually quite slow. It is fastest and easiest to land because you use your front hand and the path to the target is smallest.
Also you don't load on it so opponent has less time to react. Fastest punches are usually hooks. (fastest as in at the time of an impact your fist has highest velocity)

 

So, not size at all then?[/QUOTE]

Size means nothing

 

Torque would probably be helpful to this discussion.

 

Such a wind-up merchant

It really does show people's lack of Newtonian mechanics at an elementary stage.

 

You can be the biggest strongest guy, but if you dont know how to transfer your weight when throwing your punches, youre not going to be able to punch your way out of a paper bag. Technique, has alot to do with how power is generated, size has nothing to do with it.

 

German gov publicly released Hitlers medical records was it 6-7 years ago and they reveal that size doesnt always equal power...

 

There are several possibilities.

Sometimes it's because of accuracy. If you land a slow but solid blow in a sensitive spot like the bridge of the nose, the temple, or the liver for example, it's going to do a lot of damage. You don't even need to be a devastating power punches to hurt someone if you land a decent blow there. I'd rather take 10 blows to the chest than a single blow to a sensitive area.

Another reason is because some guys are denser. As in, their bones are thicker and they may have big fists and thick muscle which can have a weird effect when they punch. I like to compare it to a wooden hammer and a steel hammer. A wooden hammer being swung at 20 MPH would hurt like hell. But the irony is that a steel hammer going 10 MPH would hurt more because it's made of a denser material. Guys who are very heavy handed can do ridiculous damage without putting a lot of speed or snap into a shot. Natural clubbing power.

The third possibility is that the guy walked you into a punch. This happens a lot with counter punchers and guys who know how to set up very good shots that you aren't prepared for. Such a punch can be devastating even if it lacks speed because you simply didn't see it coming. They don't necessarily have to throw out a lightning fast explosive shot if they know your habits and can literally just do a basic punch and let you use your own momentum to deliver more power for them as you run right into it.

 

Some humans are just blessed with dynamite in there hands.

Some would argue Naseem Hamed didn't have A* technique but he had ridiculous power in both hands. How does a tiny fighter like that punch so much harder than much bigger fighters?

It cannot be explained with physics.

You can have very little power but if you hit a man slap bang on the chin while he's coming towards you, you can knock him out. Technique matters too
