If I push a closet that weights 800 N by a distance of 2 m on a surface without friction, the work is 1600 J. The same work is done if I push another closet that weights 400N by a distance of 4 m on a surface without friction. Can I say that I would be as tired in the first situation as in the second one, since the work is identical?
