Here's why:
* Newton's Law of Universal Gravitation: 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.
* Formula: F = G * (m1 * m2) / r^2
* 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 Proportionality: Inverse proportionality means that as one quantity increases, the other decreases proportionally. In the case of gravity, the force increases as the masses of the objects increase.
In summary: The force between two bodies is directly proportional to the product of their masses, not inversely proportional.
