# Work

Work is done whenever a force moves something.

Everyday examples of work include walking up stairs, lifting heavy objects, pulling a sledge and pushing a shopping trolley. Whenever work is done, energy is transferred from one place to another.

A man pushes a box with a force of 10 newtons to move it a distance of 2 metres

## Calculating work done

Here is the equation that relates work done, force applied, and distance moved in the direction of the force:

$work~done = force \times distance$

$W = F \times d$

where:

W is measured in joules, J

F is measured in newtons, N

d is measured in metres,m

In the example above, 10 N is applied to move the box 2 m.

Work done = 10 × 2 = 20 J
