Power vs Time
Formule
Mechanical Power
Power is the rate at which work is performed or energy is transferred.
Formula
P = W / t
One watt equals one joule per second. To convert watts to horsepower, divide by 745.7.
Exemple Résolu
A motor does 1000 J of work in 5 seconds.
- 01P = W / t
- 02P = 1000 / 5
- 03P = 200 W
- 04P = 0.2 kW
- 05P = 200 / 745.7 = 0.268 hp
Questions Fréquentes
What is the difference between power and energy?
Energy is the total amount of work done, while power is the rate at which that work is done. A 100 W bulb uses 100 joules of energy every second.
