Formula and explanation
Average power: P = (W)/(Δ t), representing the average rate at which work is done over time interval Δ t. Instantaneous power: P = F v cos θ (as Δ t → 0 ), where v is the instantaneous speed. Conditions: Constant or variable force, corresponding to different formulas. Note: Power is a physical quantity describing the rate of doing work.
