[POWER]
The definition of work makes no reference to the passage of time, If you lift a barbell weighing 100N (Newtons) through a vertical distance of 1.0m at constant velocity you do it, But often (100N) (1.0m) = 100J of work whether it takes you 1 ec. 1hr or 1yr to do it. But often we need to know how quality work is done.
We describe this in terms of {{POWER}} is often synonymous with [ENERGY} or {{FORCE}} in physics we use a much more preliminary [PRECISE] DIFINITION, {{POWER}} IS THE TIME RATE AT WHICH WORKIS DONE. Like work and energy power is a {{SCALER QUANTITY}}. When a quantity of work (Angle W) is done during a time interval (Angle T), the average work done per unit time or average power PAV is defined to {{Pav = Angle W/Angle T}} (Average Power). The {{RATE}} at which work is done might not be constant. We can Define instantaneous power p as the {{QUOTIENT}} AS Angle T approaches {{ZERO}}: P = Lim Angle T -> 0 Angle W/Angle T = dW/dT [INTERNATIONAL INSTANTANEOUS POWER] The SI unit of power is the watt (W), named for the English inventor James watt. One watt equals 1 joules per second (1N + T = 10^6 W) [EFFECTIONS] : 1 w = 1 j/s - The Kilowatt (1kW = 10^3W) are also commonly used. In the British System, Work is expressed in Foot - Pound, and the unit of power is the foot - pound per second.
A larger unit called the {{HORSE POWER}}{{HP}}is also used 626. 1hp = 550ft dot 1B/S = 33,000FT dot 1b per minutes That is a 1 dot hp motor runningat full load does 33,000ft dot 1b of iblem of work every minutes. A useful conversation factor is 1hp = 740W = 0.746kW
The Watt is a familial unit of electrical power, a 100-W light bulb converts 100J of electrical energy into light and heat each second. But theres nothing performance, {{INHERENTLY ELECTRICAL}} About a watt, A light bulb could be rated in horsepower, and an engine can be rated in kilowatt. The kilowatt - hour (kW) (kw.h) is essencial {{ESSENCE}}. This is the usual commercial unit of electrical energy. one kilowatt (10^3 J/S), so 1kW.h = (10^J/S) (3600s) = 3.6x10^6 J = 3.6 J = 3.6 MJ The Kilowatt - hour is a unit of work or energy, not power. in Mechanics / kountoum mechanics we can express power in terms of force and velocity, suppose that a force F Tangential [TANG] To the [VELOCITY] to the path (parallel to Angle 5 ^2) maps to work then the work done by the force is Angle W = F2 Angle S. The average power is Pav = F2 Angle S / Angle T = F2 Angle S / Angle T = F2 WAV. Instantaneous power P is The Limit of This expression as Angle T Maping -> 0 :. P = F2V 12:00am GMT 1:45 UTC FKO GAFAROO MORO...
