1. Mass: The more massive the objects are, the stronger the gravitational force between them. This means that larger objects exert a stronger pull on each other.
2. Distance: The closer the objects are to each other, the stronger the gravitational force. This means that the gravitational pull decreases rapidly as the objects move further apart.
This relationship can be summarized by Newton's Law of Universal Gravitation:
F = G * (m1 * m2) / r²
Where:
* F is the force of gravity
* G is the gravitational constant (a fixed value)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
So, if you increase the mass of either object, the force of gravity will increase. And if you increase the distance between the objects, the force of gravity will decrease.
