Pvt. Parts Posted March 11, 2015 Share Posted March 11, 2015 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. Quote Link to comment Share on other sites More sharing options...
Leader RedBaird Posted March 11, 2015 Leader Share Posted March 11, 2015 (edited) That would depend on how much mass they are moving, or how much they "weigh". There might be a forumula somewhere. Edited March 11, 2015 by RedBaird 1 Quote Link to comment Share on other sites More sharing options...
Leader RedBaird Posted March 11, 2015 Leader Share Posted March 11, 2015 I guess that you have already looked at posts like this one: https://www.physicsforums.com/threads/stair-climbing.111778/ Quote Link to comment Share on other sites More sharing options...
Pvt. Parts Posted March 11, 2015 Author Share Posted March 11, 2015 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.

Joshmeister Posted March 14, 2015 Share Posted March 14, 2015 Where did the .197 come from? Are you calculating work with that (W=Fd) ? If you're looking for energy as in calories, this video will help Quote Link to comment Share on other sites More sharing options...
