The force of gravitation between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Therefore, the force of gravitation between two objects is less when:

1. The masses of the objects are smaller. The greater the mass of an object, the greater its gravitational pull. Therefore, if the masses of two objects are smaller, the force of gravitation between them will be less.

2. The distance between the objects is greater. The farther apart two objects are, the weaker the force of gravitation between them. Therefore, if the distance between two objects is greater, the force of gravitation between them will be less.

For example, the force of gravitation between two people standing on Earth is much less than the force of gravitation between Earth and the Sun. This is because Earth and the Sun have much larger masses than two people, and Earth and the Sun are much farther apart than two people.
