Speed Vs Power

[PhotonGuy]

I've long held that F=MA is far too crude a formulation to apply to a complex biomechanical procedure like throwing a punch. It's misleading, and doesn't tell you anything useful for training purposes.

That particular equation takes into account acceleration which is different than speed. Acceleration is pickup.

The facts lie bare, the thread's going nowhere, not an argument to be seen
A kingdom of acceleration and it looks like you're the queen....

Power = compress and release

It takes time to have a full compressing with the whole-body unification. When you compress halfway and release for speed, you will only generate 50% power.

If you watch these 2 "power generation" videos, a punch take about 1 second to complete. In combat, 1 second can be too long.

If you watch these 2 "speed generation" videos, a punch take less than 1/4 second. But those punches may not have enough knock down power because a punch is not fully compressed.

I just want to point out that with the guy in the first video, his hands are reaching higher maximum speeds than those of the guy in the last video.
