Work Done: GCSE Physics Definition

What is work done?

In GCSE Physics, work is done when an external force is applied to an object and causes the object to move some distance.

This is described by the equation:

Where:

• = work done, measured in newton-metres (Nm)

• = force applied, measured in newtons (N)

• = distance moved, measured in metres (m)

The distance moved is in the same direction as the force applied.

Work done is equal to the energy transferred in the process. Therefore, the units of newton-metres and joules are equivalent.

It is important to note that different exam boards use different symbols for work done and distance moved:

• AQA GCSE Physics uses where = displacement, measured in metres (m) and work done is measured in joules (J) or newton-metres (Nm)

• Edexcel GCSE Physics uses where = work done, measured in joules (J)

• OCR GCSE Physics A uses where = displacement, measured in metres (m) and work done is measured in newton-metres (Nm)

• WJEC GCSE Physics uses where work, measured in joules (J) or newton-metres (Nm)
