1. Mass of the objects: The more massive the objects are, the stronger the gravitational force between them. This means that a larger object will exert a greater pull on a smaller object.
2. Distance between the objects: The farther apart the objects are, the weaker the gravitational force between them. This is an inverse square law, meaning that if you double the distance between two objects, the gravitational force between them will decrease by a factor of four.
In mathematical terms, the gravitational force between two objects can be calculated using Newton's Law of Universal Gravitation:
F = G * (m1 * m2) / r^2
Where:
* F = force of gravity
* G = gravitational constant (approximately 6.674 x 10^-11 N m^2/kg^2)
* m1 = mass of object 1
* m2 = mass of object 2
* r = distance between the centers of the two objects
So, the strength of the gravitational force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
