Either I don’t know, or I don’t care. Since the thread title isn’t asking for standard formulae, I am erring toward the side of real-world examples. Here’s another one, FIREFLY POWER. A firefly lights it’s lantern to 0.03 lumens, and a scientist (so he claims) estimates the generating power as 0.045mW. Is the estimate believable? Why or why not? —Brad

Power = Force*Speed = Force*Distance/Time = Work/Time
It doesn't matter whether the force is producing acceleration or just overcoming friction or gravity.
