Well, at least I have the effects on the road correct. :) thanks for that. thats most important, but just want to get the terminology right.
I think its coming into a philosophical debate now, which came first, the force or the power that created it. I think I understand, that even if the power creates the force, its the force that is causing the acceleration, even though the power of the act is known at the same time. (how is that for a compromise?).
So, how do we address the hp curve and the progressive time spent at different rpm as the engine accelerates over a given vehicle speed range when comparing different shaped HP curves of two engines, in the same car, with the same max HP?
