1. Mass: The more massive the objects, the stronger the gravitational force between them. This means that larger objects exert a greater pull on each other than smaller objects.
2. Distance: The closer the objects are to each other, the stronger the gravitational force. This means that the force of gravity decreases as the distance between the objects increases.
You can summarize this in the following formula:
F = G * (m1 * m2) / r^2
Where:
* F is the gravitational force
* G is the gravitational constant (approximately 6.674 x 10^-11 N m^2/kg^2)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
