Here's why:
* Newton's Law of Universal Gravitation: This law states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
* Mathematical Representation: The formula is:
* F = G * (m1 * m2) / r²
where:
* F is the force of gravity
* G is the gravitational constant
* m1 and m2 are the masses of the two objects
* r is the distance between their centers
* Inverse Square Law: The "1/r²" part of the formula is the key. This means that if you double the distance between the objects, the gravitational force becomes four times weaker (2² = 4). If you triple the distance, the force becomes nine times weaker (3² = 9).
In simpler terms, the farther apart two objects are, the weaker the pull of gravity between them.
