1. Mass: The more massive the objects are, the stronger the gravitational force between them. This is a direct relationship, meaning if you double the mass of one object, the gravitational force doubles.
2. Distance: The closer the objects are to each other, the stronger the gravitational force. This is an inverse square relationship, meaning if you double the distance between the objects, the gravitational force becomes four times weaker.
You can think of it like this: gravity is a "pulling" force between objects. The more "stuff" (mass) there is in an object, the stronger its pull. And the closer two objects are, the easier it is for their pulls to reach each other.
