Gravitational Force is Independent of the Medium
Newton's Law of Universal Gravitation states that the force of attraction between two objects with masses *m1* and *m2* separated by a distance *r* is:
```
F = G * (m1 * m2) / r^2
```
where *G* is the gravitational constant.
Key Point: This equation does not include any term related to the medium surrounding the masses.
Therefore, the ratio of forces between two masses kept at a certain distance in air to force them when in any other medium is 1:1.
Why This Matters
* Gravity is a fundamental force: It acts directly between objects regardless of the intervening medium.
* Contrast with other forces: Forces like friction or buoyancy depend heavily on the medium.
