Power measures how quickly work is done or energy is transferred — the same amount of work done faster means more power.
Power measures how quickly work is done or energy is transferred — the same amount of work done faster means more power. This calculator finds power in watts from the work done and the time it took.
A motor does 5,000 J of work in 10 seconds. Power = 5000 / 10 = 500 W.
Power = work done ÷ time taken, or force × velocity for continuous motion.
1 horsepower equals approximately 746 watts.
A motor lifting a weight over time, or an engine delivering torque at a rotational speed.
