SUMMARY
The discussion centers on calculating gravitational potential energy (P.E) between two masses in space using the formula E(grav) = -GmM / r. A participant, Billy, inquires whether the work done formula (Work = F x s) can be applied in this context. Another contributor clarifies that since the gravitational force (F) is not constant in a gravitational field, integration must be used to derive the potential energy formula, specifically through the equation dw = -F dx and integrating from infinity to a distance r.
