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

There’s is way more to punching power than trying to do mass and speed. It’s about leverage, follow-thru, balance, momentum, speed and technique. You aren’t punching a wall or uniform object so the person getting hit absorbs a blow in multiple different ways.

Punching hard is about mechanics. Much like throwing a baseball.

 

Wut?

 

It depends. Length is just an illusion of power. Girth, meanwhile, is true power..

 

Wow, if only you'd come along 13 pages ago...we could have used that kind of thinking.

 

A feather also has a design that means it won't fall in a uniform manner, like the bowling ball.

It will turn and change direction as the air moves across and around it.

The ball will simply cut through the air.

 

Maybe you should consider impulse too:

Change in momentum = forced applied x time

The reason you 'follow through' with a punch, football kick, golf swing etc is because of this equation.

A jab doesn't have the follow through of a cross say. Also consider the fact the cross involves transferring the mass of the body through the shoulders as you rotate. A jab doesn't.

There is even more to it, just think through the mechanics of each punch. Practice and feel how your balance changes with the variety of punches - you can feel where your mass goes...

sorry Dodgy,

I stopped by at my 1st available moment,
Some of us do have lives outside of these boards.

I’ll do better next time.

 

That's quite alright, Hanz, me old mate.

Just don't let it happen again...we need you here at all times to explain complex physics related questions.

 

mass x acceleration = force formula doesnt 100% apply in boxing, because we dont literally throw our hands like objects, lol, our hands are attached to the body, so punching power is more about technique. Bandeedo already explained it well. As an example you can take GGG who is not the biggest fighter in his division, nor the fastest, actually his speed is mediocre at best, but he still cracks more than bigger guys with better speed.

 

The bigger you are the more potential you have for power. That's why great HW hit hardest.
BUT you need velocity, leverage and timing in order to execute a powerful punch.
If you throw arm punches then you only have the potential power of the weight of your arms.
In order to throw a full potential punch it needs to originate in your hips and punch through the target.
Of course you are more vulnerable to a counter when you punch through and that's why some guys don't do that or get exposed.

 

You misunderstood.

I didn't say the feather has any "desires of its own".

That is a bizarre suggestion.

I think, perhaps, you thought I was being literal when I was just using words that would be easy to visualise.

For instance, when I said "cut through the air" I merely used it as way to describe something moving at speed with little resistance...not something actually cutting the air.

I'm not a scientist, so I'm using simplified language - for my benefit but also for those who, like me, won't/can't follow along when complex equations are used.

Because of the shape of a feather it will tumble and rotate, turning and rolling, because the air hitting it causes this to happen.

It catches different parts of the feather and this is what causes the change in direction.

If you make an aerodynamically efficient paper aeroplane and throw it there is a graceful flight path as the air moves across it in a uniform manner.

Screw up the wings and all of the sudden the air is meeting resistance, it can't move in a uniform way, and so the paper aeroplane hits the ground.

I hope I'm making sense?

I know what I trying to say, but it's difficult to find the right words as I'm (obviously) not an expert.

It would be so much easier to have a practical demonstration.
