Explanation:
Someone hauls a load weighing 600N through a vertical height of 10m in 20s. How much useful work does she do? ... With this equation, you can work out that the work done is 6000J / joules (Nm or Newton metres) as the force, which is 600N, multiplied by the distance, which is 10m, is 6000Nm or 6000J.
