Work (W) is measured in joules using the formula W = f · d where f is the force in newtons and d is the distance over which the force is applied in meters.

If 27 joules of work are needed to move a box a distance of 9 meters, how much force was applied to the box?

18 newtons
3 newtons
243 newtons
36 newtons

27/9 = 3

W = 27
d = 9 
f = 3
