When the force acts in the direction of the displacement, the work done is positive and is calculated as W = Fxs. If the force acts opposite to the direction of displacement, the work done is negative, and if the force is perpendicular to the displacement, no work is done.
How does the direction of force relative to displacement affect the calculation of work done?

The direction of force relative to displacement affects work done as work is calculated using the component of force in the direction of displacement. If force and displacement are parallel, maximum work is done. If they are perpendicular, no work is done. The work done is given by
W = F d cos θ.
