|
The force between two point masses is directly proportional to the product of the masses and inversely proportional to the separation between them | Newton's Law of Gravitation | 28%
|
The square of the orbital period T of a planet is directly proportional to the cube of its average distance r from the Sun | Kepler's Third Law of Planetary Motion | 15%
