It makes no difference if the weight is lifted slowly or quickly. Type the number of Horsepower (hp) you want to convert in the text box, to see the results in the table. Apart from these units, there are certain additional units that are commonly seen in physics. In the SI system of measurement, power is measured in watts (symbol: W). In physics, torque is simply the tendency of a force to turn or twist. In the International System of Units, the unit of power is the watt, equal to one joule per second. Despite its name, electromotive force is not actually a force. The current I through a conductor depends on its area A, the concentration n of charge carriers, the magnitude of the charge q of each carrier, and the magnitude of their average (or "drift") velocity v d, Current density is the amount of current flowing through a conductor divided by its area, The … In physics, power (symbol: P) is how fast work is done or energy is given from one thing to another.
