Work is said to be done when a force moves an object through a distance. If we want to quantify or measure the amount of work done, we must know the magnitude (size) of the force applied, and the distance the object was moved.

When carrying out calculations of this nature, we must be careful to use base units, in this case, the metre for distance and the Newton for force.

For example, if the force applied was 20 Newtons, and the distance moved was 1 metre, then the work done is calculated by multiplying the force by the distance.
