For rotational systems, the cross product of torque and angular velocity yields this quantity, which is equal to the dot product of force and velocity in linear systems.
This quantity's namesake factor is the ratio between real and apparent values of this quantity and is calculated by dividing resistance by impedance. This quantity's namesake gain is defined as the ratio of this quantity at a load to a source. This quantity over unit area yields intensity, and in fluid systems this quantity equals pressure times the volumetric flow rate. This is the product of the electric potential difference and the current. For rotational systems, the cross product of torque and angular velocity yields this quantity, which is equal to the dot product of force and velocity in linear systems. For 10 points, name this amount of work done per unit time, whose SI unit is the watt.
