Physics in walking up the stairs
· 4,275 views
i don't know one person who actually enjoys walking up the stairs. in fact, i hear people complain about having to climb 3 flights of stairs multiple times a day! yet why is it so miserable? well in order to lift yourself up one step, there needs to be a force of at least your weight in order to go up the step. when there is a large amount of steps, that's a lot of work that is done in order for you to walk up the steps. since work is being done because a force is causing a displacement, that also means that there has been a change in energy. As you get higher up the steps you increase your potential energy. it's true, physics is really anywhere.
