1. Mass: The more massive the objects are, the stronger the gravitational force between them. This means a larger object will exert a stronger pull than a smaller object.
2. Distance: The closer the objects are to each other, the stronger the gravitational force between them. As the distance between objects increases, the gravitational force weakens rapidly.
The relationship between these quantities is described by Newton's Law of Universal Gravitation:
* F = G * (m1 * m2) / r^2
Where:
* F is the force of gravity
* G is the gravitational constant (a constant value)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
