A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force (see Figure below). Let us take it that the force acts on the object through the displacement. What is the work done in this case ?

Explanation

We know that : `"Work done" = "Force " xx " Displacement"`
Or `W = F xx s`
Here Force,`F = 7 N`
And Displacement,`s = 8 m`
So, `W = 7 xx 8 J`
or `W = 56 J`
Thus, the work done in this case is 56 joules.
