1. If your are walking down a flight of stairs would the sign of work be negative, positive or zero?
2. Well work =FCOS Theta Delta X.
3. SO I think it would be negative. My reasoning is that the normal force of the person walking down a flight of stairs is in the opposite direction of the gravitational force, so the result is negative work. Does this logic sound correct?
