And let me add my endorsement to metzgeer's comment: this kind of problem is not well suited to a "pure" physics approach. | |

| Jun 21, 2011 at 1:38 | comment | added | Preet Sangha | Thank you. I'm looking to calculate an energy delta not the exact amount. Also lets assume friction is zero in the first case. I'm happy for a simple answer that assumes some ideals | |

| Jun 21, 2011 at 1:21 | comment | added | metzgeer | I think this may be a biological question, as an animal will expend energy just standing still and holding a weight above the ground, whereas an inanimate object like a table does no work. From a physics point of view, you only do work against friction and the vertical line of gravity. And I can't see how to calculate friction for a runner. | |
