F = G(m1 x m2)/(d)^2
If you double the mass of one object and double the distance between the center of the two objects what happens to the force?
If you double the mass of each object and double the distance between them what happens to the force?

drwls,
Part 1: the numerator gets multiplied by 2 while the denominator gets multiplied by 4. That is like multiplying the original number by 2/4
You can figure that out.
Part 2. 2*2/2^2 = 1 is the factor to apply. What happens when you multiply by 1?
