- Gravity is also affected by mass. which is the amount
of matter in an object. As the amount of mass increases, the force of gravity
between two objects

As the amount of mass increases, the force of gravity between two objects increases.

Explanation:

Every object in the universe attract every other object in the universe with a force which is proportional to the product of their masses and inversely proportional to the square of distance between them.

This force is called the force of gravitation or gravity.

As we can see, mass is directly proportional to the force of gravitation, so when mass increases, the force of gravitation increases too.
