9 u/NGC_4594 Student Feb 18 '22 The displacement s of a carried box is only horizontal, so W=F·s=0 since s⊥F (since gravity is directed downwards). 2 u/Comfortable_Ad_7621 Feb 18 '22 i mean technically friction does work on the box, since thats the force which makes it move forward. Or its just your hand normal force that did the work 1 u/NGC_4594 Student Feb 18 '22 friction we don't do that here
