When two objects are near each other, increasing one object’s mass would cause the gravitational force of the object to increase.
The formula for gravitational force (F) is
![F = (GmM)/(d^(2) )\\](https://img.qammunity.org/2019/formulas/chemistry/college/nsooha7hspdpxl2lnf3ge621eagrznny0v.png)
where m and M are the masses of the two objects, d is the distance between their centres, and G is the gravitational constant.
If we hold M and d constant, we can write
, where
![k = (GM)/( d^(2))\\](https://img.qammunity.org/2019/formulas/chemistry/college/ljmg5u7mvtjepr0cs6cl8tw2kp5jl9j0fb.png)
Thus, gravitational force is directly proportional to the mass of the object.
If you increase the mass of an object, you increase its gravitational force.
