Newton's Law of Universal Gravitation:
* F = G * (m1 * m2) / r²
Where:
* F is the force of gravitational attraction
* G is the gravitational constant (approximately 6.674 × 10⁻¹¹ N⋅m²/kg²)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
How Force Varies with Separation:
* Inverse Square Law: The force of gravity is inversely proportional to the square of the distance between the objects. This means:
* If you double the distance, the force becomes four times weaker.
* If you triple the distance, the force becomes nine times weaker.
Important Considerations:
* Material Doesn't Directly Affect Gravity: The material composition of the objects doesn't directly influence the gravitational force between them. The only factors that matter are their masses and the distance between their centers.
* Small Forces: Gravitational attraction is a very weak force, especially at everyday distances. It only becomes significant when dealing with extremely massive objects like planets or stars.
In Summary:
The force of attraction between two masses made of the same material will decrease rapidly as the distance between them increases, following an inverse square law. The material itself doesn't affect the gravitational force, only the masses and the distance.
