I keep getting “Power” questions wrong in Work, Energy & Power. What's the trap?
confusing power (how fast work is done) with energy (the total work).
The usual trap: confusing power (how fast work is done) with energy (the total work). How to avoid it: a strong engine does the same work faster — more power, not more energy. Go back to the definition — the rate of doing work, P = W/t = F·v.
