A pressure wave is a more precise description. It's a sudden increase in pressure in the tissue, not just the water content of the tissue, and this pressure increase propagates through the tissue. Direct applied force and momentum transfer are redundant, as force is equal to the rate of momentum transfer, but I agree that the wound channel is determined by the amount of applied force and the extent to which that force propagates through the tissue as a pressure wave.

Momentum is mass x velocity, whereas kinetic energy uses the square of velocity.

Seems to me killing power is a rather complicated mix of forces.

DF

Momentum = mv
Net force = ma

So force is equal to the time derivative of momentum, or in other words, the time rate of change of momentum.
