Simple Question?? Here is a question I argued with my family for over two hours Christmas evening... If a man is standing on the edge of a plateau overlooking a 1000' cliff, does he have the SAME potential energy of a man of the same mass at the same elevation on the plateau but 2 miles from the cliff? Now, what if you put an object on the edge of a ramp, does it have the same PE as an object of the same mass on the edge of the ramp but inside of an immovable box? Would the box change the PE? We have an "airline ticket to Florida" wager on this arguement so any details would be appreciated. Thanks!!!
