The calculation of power, whether the power of a wind power an electric motor power or mechanical power connects a quantity of energy (work) obtained with a duration (time).

The international unit of power is the watt, its multiple is the kilowatt.

1 watt = 1 joule for a second

work unit is the Joule

work is the result of an applied force on an object multiplied by the distance traveled by the object during the application of this force. We consider that this force is applied in the direction of motion.

Work = Force x Distance

If this force is at an angle with the direction of motion we have

Work = Force x Distance x cosine angle

Work in joules, distance in meters, force in Newtons
