I think it is included in the mass with which the start
So if I were to compare an identical mass of a flat slab and a sphere with the same start mass in a uniform gravitational field for say 60 million years they would still be the same?
The force to maintain the structure of the sphere for instance, doesn't that cost more energy than the force that maintains the slab in such a gravitational field?
