    clearscience: Hey there, Anonymous. The Clear Science staff isn’t permitted to answer homework questions. However, this one just happens to be relevant to mankind’s use of energy, which is what we’re talking about. The precise, scientific definition of work is what’s important here. And that’s why even though you can really wear yourself out pushing on a wall, the answer is you did no work. Also since WORK is FORCE x DISTANCE, and this this case, although there was force applied, there was distance made thus making the work 0.
