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. This means that if you increase the mass of either object, the force of gravity between them will also increase.
* Inverse Square Law: The force of gravity also depends on the distance between the objects. The force decreases rapidly as the distance between the objects increases (following an inverse square relationship).
In summary: The more massive the objects, the stronger the gravitational force between them. The closer the objects are to each other, the stronger the force.
