Question

Prove that gravitational potential energy is conserved.

Answer 1

Answer:

It turns out that it makes sense to do this because as the distance r becomes large, the gravitational force tends rapidly towards zero. ... Because energy is conserved, we lose gravitational potential energy to account for this—in other words, U g U_g UgU, start subscript, g, end subscript becomes more negative.
