Clarification of a concept


Just to clarify, carrying a box in most cases is not considered work. For something to be considered work, the force you apply and the distance you apply must be in the same direction.

In the case of carrying the box, you are using a vertical force to lift it, while you are going horizontally in distance. This means that zero work is being done as the force and distance are not applied in the same direction.

Examples: Pushing a car horizontally from rest; shooting a bullet (the powder does the work); walking up stairs; sawing a log.
