Derivative of power physics

WebP = d W d t. If the power is constant over a time interval, the average power for that interval equals the instantaneous power, and the work done by the agent supplying the power is W = P Δt W = P Δ t. If the power during an interval varies with time, then the work done is the time integral of the power, W = ∫ P dt. W = ∫ P d t.
