A moon is located at 1 unit out from the planet it orbits. If that moon was orbiting at 2 units out from the planet, how much would the gravitational force on the moon be compared to its distance at 1 unit?
41 of the original force
61 of the original force
twice as much
4 times as much
What happens to Gravitational force if I double both of the masses but don't change their distance?
doubles
half as big
4 times bigger
41 as much or 4 time smaller
