* Mass of the objects: The more massive the objects, the stronger the gravitational force between them. This relationship is directly proportional, meaning if you double the mass of one object, the force of gravity doubles.
* Distance between the objects: The closer the objects are, the stronger the gravitational force between them. This relationship is inversely proportional, meaning if you double the distance between the objects, the force of gravity decreases by a factor of four.
You can summarize these relationships with the following equation, known as Newton's Law of Universal Gravitation:
F = G * (m1 * m2) / r²
Where:
* F is the force of gravity between the objects
* G is the gravitational constant (approximately 6.674 × 10⁻¹¹ N⋅m²/kg²)
* m1 is the mass of the first object
* m2 is the mass of the second object
* r is the distance between the centers of the two objects
This equation shows that the force of gravity is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
