I am a bit confused.
Nugatory says that it will still be 20 J as energy created will contribute to the gravity and potential energy does not really change,
While DaleSpan says potential energy of the stone does reduce and nuclear fission will not be e=mc^2 but will produce equivalent...
Conservation of mass from chemistry and conservation of energy from physics were combined into conservation of mass and energy as special relativity proved mass-energy equivalence.
In short, if we count all the mass in using E=mc^2, total sum of energy is always conserved even with nuclear...
