In the example above, 10 N is applied to move the box 2 m. Work done = 10 × 2 = 20 J The triangle above will help you to rearrange the equation. Work done has the same units as energy - joules.
But for a quick definition, work done is when a force causes an object to move through a distance, when a force transfers energy from one store to another. So let's look at an example of how work ...
