Tyson VS Foreman on the heavybag

[Simurgh]

good.

and the maths definition of mech energy is?

Integral of the energy field gradient (in this case force) and the distance increment/differential

Well, teacher?

right.


and what do you think the OP is interested in specifically?

The physical force transferred to the object in a single punch's impact?

Or the distance increment moved in transferring the fist to the opponent?

Or perhaps the total energy needed to move fists to and fro over a time period?

It's not a pure transfer of the momentum. So it's not the first. (m*a).

It can't be the second as the second is dependent on the repulsion force of the target. That would mean that same punch on the 'harder' face/target would have a less power than on the 'softer' face/target.

It's not the third either as it doesn't depend if my fist is traveling 1 second or 2 seconds to your face as long it's at the same velocity.

Mostly it's related to kinetic energy of the punch. Linearly proportional to the mass, and proportional to square of the velocity. This means that velocity is the most important parameter. They don't say "speed kills" for nothing.

very good, your knowledge of A lvl physics is intact.

I would add that relative velocity is the key as opposed to velocity alone when considering energy itself, Foremans bag was stationary, Tysons was swinging free (although hefty).

I know slightly more than A lvl physics It's not by chance I l support the smartest boxers out there.

Of course, all the values are relative. Pacman throwing himself at Marquez fist
did a good amount of damage in itself.

very good, have a gold star.

The fist of course decelerates when it hits the bag, I expect you would agree.

I received the gold stars when it was relevant.

Bag decelerates, but it doesn't matter. The punching power doesn't depend on the target. Tyson could have hit the wall with the same power punch it wouldn't move at all...

Only case when it does matter is when the bag is moving before the punch. So if someone pushes the bag towards the punch of course the effective power is greater.

Here we have Foreman on the heavybag

Here we have Tyson on the Heavy bag

http://www.youtube.com/watch?feature=player_detailpage&v=G2rpfX7Gi6Y

Tyson prime weighs 218 -221 lbs

Foreman prime weighs 220 -225 lbs

So barely any difference in wieght.

But a huge difference in speed as you can see for yourself.

Speed is twice as important as body weight in a punch and these 2 factors are the only factors that contribute to power. Speed squared times mass = power or something like that.

So how the hell does Foreman hit harder than Tyson?

Ali was about the same weight as well and we know he's faster than Foreman, where's the argument for his superior punching power? Same with Chris Byrd.

yes, the free movement of a free swinging bag affects deceleration.

Though theres nothing wrong with what you are saying, after all its pretty much direct quoting from a textbook.

Haha... Only textbook I am quoting from is on my shoulders

You fail.
