Answer 1

Since this is not my area of expertise, I searched Google under the key words "<I>'gravitational potential energies' mass altitude</I>" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
