Exemplary Define Power In Physics

While instantaneous power is the limiting value of average power.

Define power in physics. The SI unit of power is Watt W which is joules per second Js. Here we present flashcard on Define Power to you. The standard metric unit of power is the Watt.

For example when a powerful car accelerates speedily it does a large amount of work which means it exhausts large amounts of fuel in a short time. In physics power is the amount of energy transferred or converted per unit time. Here electrical energy can be either kinetic energy or potential energy.

In physics the rate of transfer of electrical energy by an electrical circuit per unit time is called electrical power. For historical reasons the horsepower is occasionally used to. The power of this event would be the work done by gravity on the mass divided by the amount of time it took to reach the ground.

P is the amount of work done per unit of time. It is a measure of the rate at which work is done or similarly at which energy is transferred. 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.

In physics power is the rate at which energy is transferred used or transformed. It is the amount of energy transferred or converted per unit time where large power means a large amount of work or energy. Electric power from the definition of power.

Sometimes the power of motor vehicles and other machines is given in terms of Horsepower hp which is approximately equal to 7457 watts. Power is a scalar quantity. Thus a Watt is equivalent to a Joulesecond.
