where F and s are the magnitudes of the associated vectors and is the angle between the force and the displacement.
So for example, consider the applied force: This force is parallel to the (level) floor, so logic tells us that the applied force is in the direction of the displacement. Thus the angle between the applied force and the displacement is 0 degrees. Thus
You do the rest. (Yes it is possible for a force to do no work, or even negative work.)
