# Is power the rate at which work is done?

## Is power the rate at which work is done?

Power is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation. The standard metric unit of power is the Watt.

What is the power of work done?

Power is the rate at which work is done (measured in watts (W)), in other words the work done per second. It turns out that: Power = Force × Velocity.

### Is power work done by time?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

Why power is a rate?

Power is the rate at which work is done. Because work is energy transfer, power is also the rate at which energy is expended. A 60-W light bulb, for example, expends 60 J of energy per second. Great power means a large amount of work or energy developed in a short time.

#### Is the rate of doing work and energy the same?
