# What SI units are used to measure power?

##### 1 Answer

The SI unit for power is the watt.

#### Explanation:

The **watt** (W) is the SI derived unit for power. It comes from the SI base units.

**Velocity** is the rate at which an object travels.

The units of velocity are metres per second (m/s).

**Acceleration** is the rate at which an object changes its velocity.

The units of acceleration are metres per second squared (

**Force** is any influence that tends to change the motion of an object. Force = mass × acceleration.

The **newton** (N) is the force needed to accelerate up a mass of 1 kg by

**Work** is the action of a force through a distance.

The units of work are

**Energy** is the ability to do work. It has the same units as work. The SI unit for energy is the joule (J).

**Power** is the measure of how much energy or work is used per unit time.

The SI unit of power is joules per second (J/s) or Watts (W).

In summary,
