Gravitation Problems Name: _____________________ Physics Pd: _____ ? The gravitational force between two asteroids 1200 km apart is 8400 N. Find the following changes in gravity. ? What is the force between them if the distance is 3600 km? ? What is the force between them if the distance is 600 km? ? Our Milky Way galaxy is very similar to our neighboring galaxy Andromeda. Consider that each galaxy contains approximately 4.0 x 1011 stars each star having an average mass of 2.0 x 1030 kg. ? If the gravitational pull of Andromeda is 2.4 x 1030 N, how far away is Andromeda? ? How many light years away is the Andromeda Galaxy? (Note there are 365.25 days per year and light travels at 3.0 x 108 m/s).
