science question

Before anyone says it, I know this should be in the science section but I know more people check the spam section. My question is however, how much energy, in joules, it takes for a human to climb one stair (assuming the stair is 7.75 inches tall). If you don't have an answer an explanation on how you might find the answer would be just as good. I was thinking it could be how much work in joules someone does for one step but I had trouble on how to equate that.

That would depend on how much mass they are moving, or how much they "weigh".

 

There might be a forumula somewhere.  :)

I was using the average weight of a 17 year old which is 64.41 kg so the force is 631.218 N. So then the work would be 631.218 * .197 = 127.35 joules for one step? I'm not looking into the metabolising yet so that is out of the question. I'm not to sure if that would be it though.
