Exam 5 SAR Physics AM Kolchin 1. Universal Law of Gravitation: F g = G m 1 m 2 r 2 where: F g = the gravitational force between two objects (in N ). m 1 and m 2 are masses of the objects (in kg ). r is the distance between the centers of gravity of the two objects (in m ). G = 6 . 67 * 10 - 11 N · m 2 /kg 2 ; ”Big G”. 2. Universal Law of Gravitation applied to a planet’s sur- face . F g = G m M planet R 2 planet where: F g = the gravitational force of the planet on an object
