## 07. Gravitation

[spoiler title="Gravitational Field" open="yes"] Newton’s Law of Gravitation states that the gravitational force between two point masses is directly proportional to the product of their masses and inversely proportional to the square of their separation, i.e. where G is the gravitational constant 6.67 10-11 N kg-2m2, m1 and m2 are the masses and r is the
