Tom used more Force but over a shorter distance. Tom and Claudia both did the same amount of work.

In this scenario, we can tell that Tom used more force.


We can tell this is correct because Tom did not use any shortcuts like Claudia did. Claudia placed her heavy box on a ramp that then transferred her box to where the shelves are. After that, all she had to is put the box on the shelf.
