When we lift a heavy box to a higher position, energy from our bodies(chemical energy) is lost and there is energy gain(potential energy) in the box.
After, when we release the box from that position to the original one(lower position), there is P.E. lost in the box. So where does lost energy go?
We gain energy from the box!? I think it is impossible...
