Calculation is trivial? I would not be paying homage to the Physics gods on this forum if calculation was so trivial. I think you folks are missing something here. Each one of these formulas you provided REQUIRE a distance. But when you make the distance 0, which what it would be when an...

Alright, if PE of an object at infinite distance is ZERO, what is it when it rests at the ground potential? You see, classic physics cannot calculate this. But the resting weight DOES exert downward energy, as common sense tells you. I want to know an energy figure, versus weight or force...

Maybe i am looking at things wrong, but it seems that classic physics cannot tell me how much gravitational energy an object has at "rest", when it is at the ground potential- at zero. Example. I have a table. I place a 100 kg object on the table. What is the gravitational energy of the...
