* Increase the distance between the objects: The force of gravity is inversely proportional to the square of the distance between the objects. This means that if you double the distance, the gravitational force becomes four times weaker.
* Decrease the mass of one or both objects: The force of gravity is directly proportional to the product of the masses of the objects. This means that if you reduce the mass of one or both objects, the gravitational force between them will decrease.
