Speed Vs Power

[Wing Woo Gar]

But it was not the equation of force, it was the equation of power, and it is surely correct.

Power is energy/time, and force*distance = energy, so power = energy/time = force * distance/time = force * velocity

Applying a certain FORCE at a certain speed in a given direction defiens the power output (energy transfer per unit time).

But this velocity is not the same as the velocity of the fist before impact, it is the speed during impact, througout the contacttime - this is where energy is transferred. And if there is little mass behind the first, it will stop quickly and "energy transfer" is low even if the transient peak force may be high.

Very well said, I stand corrected.

Where:
W+t+F = What the F**k = what I think when I see formulas re: MA

My understanding is:

Where:
IF = Impact Force
fc = facial contact

Then IF + fc = n$ @ the MD

Hey, formulas are pretty fun after all.

I knew someone that insisted to call forms(kata/taolu) as formulas…. I too think formulas are fun

If you punch with just your arm your hand will be moving at the speed of your arm, if you put your hips into it your hand will be moving with the speed of your arm plus the speed of your hips, for a more in-depth explanation see post #50.

No, but this should create more Force, assuming the technique it correct.
