Thanks! I'll check back on it when I can get my hands on a windows, looks great so far.

Does anyone know of a good site to visualize the effects of relativity? It would hopefully include sliders to adjust the variables and show the related shift on the graph. Merci beaucoup!! =D

When you are lifting the object you are doing work (W=f*d=m*g*h). By lifting the object you have done POSITIVE work. When it falls back to the ground the EARTH does positive work and you have done NEGATIVE work. This sums to having done ZERO work. Work is just an easy way of saying change in energy. Hope I've helped.
