No, I don't think so because F isn't a constant in a G-field, but we can use integration to derive the formula, E(grav) = -GmM / r.Originally posted by BillyCheung
Dear all
I know that E(grav) = -GmM / r, Can I use Work done = F x s to calculate the P.E between two mass of the space? Thank a lot.Good Bye

To calculate the potential energy between two masses in space, you can use the formula PE = m1 x m2 x G / r, where m1 and m2 are the masses of the objects, G is the gravitational constant, and r is the distance between the two objects.
Potential energy between two masses in space represents the amount of energy that could be released if the two objects were to move closer together due to gravitational forces. It is an important concept in understanding the behavior of objects in space.
Yes, potential energy between two masses in space can be negative if the two objects are moving away from each other. This indicates a decrease in the potential energy of the system.
The work done on an object by a force is equal to the change in potential energy of the object. In the case of two masses in space, if work is done to move the objects closer together, the potential energy between them increases. If work is done to move the objects farther apart, the potential energy decreases.
Yes, potential energy between two masses in space can be converted into other forms of energy. For example, if the two objects were to move closer together, their potential energy would decrease and their kinetic energy (energy of motion) would increase. This conversion of energy is a fundamental concept in physics.
