Work is defined as the force applied to an object multiplied by the distance the object moves in the direction of the force. This is represented by the formula:

Work (W) = Force (F) x Distance (d)

And the unit of measurement for work is indeed the joule (J).

Here's why the joule is used:

* 1 joule (J) = 1 newton (N) x 1 meter (m)

This means that if you apply a force of 1 newton to an object and move it 1 meter in the direction of the force, you've done 1 joule of work.
