What is Work, Energy and Power?
Work
Unit The SI unit of energy is Joules (J).
Power
Definition Power is defined as the rate at which work is done.

### What is the formula for work power?

Work and Power Difference in Tabular Form

Criteria Work
Formula Total Work Done (W) = Power (P) x Time (t) or Work = Displacement x Force
Measurement Unit (SI unit) The standard unit of work is the Joule denoted as (J). Furthermore, you can measure work in electron volt (eV), kWh, GWh, and MWh

#### What is the formula and units for power and work?

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. One horsepower is the amount of work a horse can do in 1 minute, which equals 745 watts of power.

What is work done power?

Difference Between Work and Power The SI unit of work is Joule (J). The SI unit of power is Watt (W). The formula for calculating the force is Work = Force * Displacement. The formula of calculating power = Work/Time. Work can be done in various other measures like kWh, MWh, GWh, and volt (eV).

Is joule a unit of power?

1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts.

## What is the unit of power work and energy respectively?

watt is the unit of power any units of work (or energy) and time can be used to generate a unit of power. The International System uses joules [J] and seconds [s] for these, respectively. A joule per second is called a watt [W] in honor of the Scottish mechanical engineer James Watt (1736–1819).

### How is work related to power?

2 Answers. Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.

#### How is work equal to QV?

Work is a measure of energy in joules (J). When we play with batteries we usually talk about electrical potential (V) and current (I) . To get work done by a battery you need to know the total charge used (Q) used and the voltage (V), and plug it into W = QV to get work.

How is work equal to VQ?

Answer and Explanation: The equation W=VQ W = V Q represents the amount of work done by an electric current.

What is joule work?

joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
