Power (physics)
Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt (symbol W), equal to one joule per second (J/s). Power is a scalar quantity. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element.
