Excuse me if this question is stupid or naive.
If there is a body in space, what is the total energy of that body?
If initially the K.E of that body was zero and then I pushed it in a certain direction .. it will keep moving until it reaches another body that have a certain gravity ( Earth for example ) and in this case it has P.E
but if I pushed it in another direction ( with the same force ) .. it will keep moving until it reaches another body ( sun for example ) and in this case it will gain also P.E but with a different value
does not that mean that in the second case the amount of total energy was greater ?
