      So everything in the universe that has a mass (weight) has its own attractive force called gravitational pull or gravity. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn’t very strong, since people aren’t very massive. When you look at really large masses, like the Earth and Moon, the gravitational pull becomes very strong. The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface.
