ninjamunky Posted September 9, 2008 Share Posted September 9, 2008 I'm trying to do some homework stuff and I need different opinions. I'm given the masses of both objects, the radii of both objects, and the distance between them. Do I use the distance as r in the gravitation equation or do I need to add each radius to the distance in order to get the distance from midpoint to midpoint... I thought the distance given was from center to center....... Link to comment Share on other sites More sharing options...

Therefore, if you wanted the centre to centre measurement it would be the sum of the 1st objects radius plus the distance plus the radius of the 2nd object.
