Velocity response is the convenient quantity for impulse power

Evidence

Resonance for an oscillator corresponds to alignment (in-phase condition) of force and velocity. But force causes acceleration, which increases the velocity, so resonance corresponds to constructive addition of velocity to preexisting velocity. This applies universally, to a single oscillator, a complex structure such as a string, a membrane, a plate, a solid, and even to air. — Eric J.

If the force is applied slowly, acceleration is weak. The force is then usually governed by compressibility or springiness, which therefore gives stiffness-dominated impedance. If a force is applied suddenly, the object hardly has time to move and sense its stiffness, but the mass of the object is felt immediately; the impedance is mass dominated. — Eric J.
