SUMMARY
This discussion centers on the relationship between gravitational force and the motion of masses within a gravitational field. The participants clarify that gravitational force, described by the equation F(t) = Gm1m2/r(t)^2, is instantaneous and depends solely on the mass and distance, not on the velocity or momentum of the objects involved. They emphasize that Newton's third law applies to the interaction between two masses, where the gravitational force acts at their centers of mass. The conversation concludes that variations in momentum do not affect the gravitational force experienced by a mass at a specific radius.
