What happens to the gravitational force between two objects as mass increases?

Answer 1

Formula for the force of gravity:

F = G( m₁ * m₂ ) / d²

where:

F = force

G = universal gravitational constant

m₁ & m₂ are the 2 masses

d is the distance

If one mass is increased by 10%, the force increases by ~20%. If BOTH masses are increased by 10%, the force increases by almost 50%.

(to be precise, the factor in the first case is 1.1^2 = 1.21. In the second case, 1.1^4 = 1.46)
