- Homework Statement
- When considering 2 masses in space, both of mass M and radius r separated by a large distance, is their kinetic energy (ie loss of gravitational potential energy) =(GM^2)/(2r) or is it twice that value?
When you calculate the gravitational potential energy, is that the GPE of the whole system or of the individual object, and the total gravitational potential energy is 2 times that value?

- GMm/r
