Yea hi, I have a little question here regarding COE.
If I climb up a very high tower or a very high place, using [tex]E_p=mgh[/tex], I would have a very high potential energy. But say, if I climb down the tower using a flight of stairs very slowly, I would actually have a very low average velocity. Because velocity= displacement/time and my time taken is very huge.
But using [tex]E_{k}= \frac {1}{2}mv^2[/tex], the kinetic energy I gain is very small. So where is this energy "siphoned" off to?
