In physics however, it has a very specific meaning. It is a measure of the rate at which work is done (or similarly, at which energy is transferred). Power is the rate at which work is done or the rate at which energy is transfered from one place to another or transformed from one type to another. Power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t —or W / t. A given amount of work can be done by a low-powered motor in a long time or by a high-powered motor in a short time.

Power is associated by many people with electricity. Knowing that power is the rate of energy use or energy conversion, what is the expression for electric power? Power transmission lines might come to mind. We also think of lightbulbs in terms of their power ratings in watts. Let us compare a 25-W bulb with a 60-W bulb. (See Figure 1(a).) In physics, power is the rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted per unit time.

In physics, an electric power measure of the rate of electrical energy transfer by an electric circuit per unit time. Denoted by P and measured using the SI unit of power is the watt or one joule per second. Electric power is commonly supplied by sources such as electric batteries and produced by electric generators. Work Energy Power Work, Energy and Power Work, energy and power are the most used terms in Physics. They are probably the first thing you learn in your Physics class.

Literature Summaries · Fun Games · Home > Formulas > Physics Formulas > Power Formula Power is a rate at which work is done, or energy is used. The unit of power is the Watt (W), which is equal to a Joul

The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second. For historical reasons, the horsepower is occasionally used to describe the power delivered by a machine. Science · Physics library · Work and energy · Work and energy What is power? Learn what power means and how we use it to describe the rate of energy transfer.

In 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, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

They are probably the first thing you learn in your Physics class. In physics, power is used to describe the rate at which energy is used. In other words, it is a measurement of how fast you are using energy. The equation that describes power is: Power = Work ÷ Time When it comes to work in physics, you’re sure to see problems involving power, which is the amount of work being done in a certain amount of time. Here’s the equation for power, P: W equals force along the direction of travel times distance, so you could write the equation for power this way: where […] (ii) power developed by him Solution. (i) Work done is given by W = F . s Here, F = mg = 100 × 10 = 1000 N W = 1000 N × 3 m = 3000 joule (ii) Now, , where W = 3000 J and t = 10 s ∴ P = 3000J/10s = 300 W Example : 10 A water pump raises 60 liters of water through a height of 20 m in 5 s.
