What does "weight" mean?

[Which Doctor]

Usually the heavier fighter hits harder, why? For example, if we have a guy like Anthony Johnson who is 205 made of mostly pure muscle and a guy like Roy Nelson who's heavier but made mostly of fat. What does weight mean then? That Roy is simply harder to push off? Why would extra fat make you hit harder?

First I'm going to drop a frozen pea on your face, then a cannon ball, then a load.

Which do think will hurt the most?

I just defied physics, no?

Weight | Define Weight at Dictionary.com
www.dictionary.com/browse/weight

the amount or quantity of heaviness or mass; amount a thing weighs. ... the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity: commonly taken, in a region of constant gravitational acceleration, as a measure of mass.

As others have stated Weight is basically Mass x Gravity. Apart from Apollo 13, we haven't had fights take place anywhere else where Gravity might be appreciably different.

When hitting harder, you also have to consider: technique, force, inertia, and sectional density. So actually, there's much more going on to the strength of one's punches beyond one guy being bigger than the other.

Why are fat people strong? I think the question is why are some strong people fat? The answer is diet.

It's more about momentum. Lets' say that two fighters of different sizes generate the same amount of force throwing their punch with the same speed. The bigger fighter will have more momentum behind his punch because of his higher mass. Momentum = mass x velocity. Imagine the difference between getting hit by a tennis ball at 50 mph and by a bowling ball at the same speed.

 

[Thy]

force = mass x (velocity / time) = (mass x velocity) / time = momentum / time

 

[Captain_Dammitt]

a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.

 

[Grijswaarde]

If big mass + speed equals big force in punches mma

then why in the strongman competitions a few of the guys looks fat (BIG belly etc), does this also help lift heavy stuff and other strenth tests?

No. They just ALWAYS eat more than they need so they don't miss any gains. And that is also the reason they are so strong, along with training with low reps in general.

who says it does?

bigger fighters (not exclusively hw) will hit harder cause they put more mass behind their punches

now lets go back to basic physics

mass x acceleration = force

now you can see why rumble can generate same or ever greater force as nelson, while mighty mouse cant

also there are other factors like size of hands/wrists, placement of the punch, technique, body type...

They're mostly solid massive muscle plus a layer of fat to fuel the muscle.

Body builders are not strongmen because they have no fat to fuel their exertions.

w(eight) = m(ass) x g(ravity)

Kim Kardashian must be like 400 pounds.

 

[alaskamma]

Force=Mass times acceleration. So yes strength could help you move your fist faster(although there's much more than strength to punching hard) but the more mass you have behind the punch= more power.

 

[Ar145984]

So basically, if I eat a shit load of food to get very fat I should be considerably stronger than a guy who lifts weights but is 30 pounds lighter, correct?

Putting aside the issue of the mass of the fist making a difference (this is why it can be more effective to hold a roll of quarters in ones fist when punching someone), I'll speculate on the possibility of bodyfat weight helping a punch to be more effective:

There is no increase of actual strength due to bodyfat, so it must be about something else (if it exists). More fat means more mass means more inertia, and a body with more inertia will disperse less force by rebounding away from the opponent during the collision of a strike. Lets consider a large person and a smaller person striking with equal strength. A small person may bounce backward if he hits a large person hard enough, and the force that bounces him back is lost to being able to affect the opponent. A large person striking a smaller person won't bounce backward (or will do so less) because the striker's more massive body has more inertia inhibiting the bounce backward. In this way more force from the punch affects the person being punched. That's my guess.
