I'm no physicist but this really doesn't make sense to me. Simple newtonian physics says that gravity is dependant on mass and that an object with more mass will have more gravity, right? well here's an equation I'm sure most of you are familiar with... F = G*m1*m2/r^2 heres my problem... m1 = 20 m2 = 1 r = 10 then F will = .2G another example... m1 = 19 m2 = 2 r = 10 then F will = .38G In each example the mass of m1 and m2 add up to 21 and yet the gravitational force (F) is different. What is the rationale behind this? I thought all objects with the same mass had the same gravitational force no matter how you diveded them (assuming the same r value).
