* Mass of the bodies: The more massive the bodies, the stronger the gravitational force between them. This relationship is directly proportional, meaning if you double the mass of one body, the force doubles.
* Distance between the bodies: The closer the bodies are, the stronger the gravitational force. This relationship is inversely proportional, meaning if you double the distance between the bodies, the force becomes four times weaker (since it's squared).
These relationships are summarized in Newton's Law of Universal Gravitation:
F = G * (m1 * m2) / r²
Where:
* F is the force of gravity
* G is the gravitational constant (approximately 6.674 × 10⁻¹¹ N⋅m²/kg²)
* m1 and m2 are the masses of the two bodies
* r is the distance between the centers of the two bodies
So, in essence, the gravitational force is stronger between heavier objects and weaker when they are further apart.
