1. The problem statement, all variables and given/known data How would one go about calculating the increasing gravitational attraction between objects, one assumed for the purpose of the calculation to be motionless, and the other moving towards it according to the gravitational attraction.? 2. Relevant equations F = GMm/r^2 3. The attempt at a solution The above formula gives the gravitational attraction between objects at a set distance, but in order to know the attraction at multiple points one would have to go throught the entire equation for each new distance. I would assume such a formula would involve the inverse square law, although any guess on my part. as to what that formula would be, would be just that, a guess. Thank's in advance for your help.
