The gravitational force between two objects increases when their masses are increased.

Here's why:

* Newton's Law of Universal Gravitation: This law states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

* Mathematical Representation:

* F = G * (m1 * m2) / r²

* F = Force of gravity

* G = Gravitational constant

* m1 and m2 = Masses of the objects

* r = Distance between the centers of the objects

Key Takeaway: If you increase either m1 or m2 (or both), the force of gravity (F) will also increase proportionally.
