If everything has gravity why aren't you noticeably pulled by gravity of a mountain or a building?

Answer 1

In fact you are attracted to the building's mass, but by a very tiny quantity.

A number of experiments have been devised to measure this force, and those of Mitchell, and of Cavendish are notable. (Check out Cavendish balance.)

One experiment, the Schiehallion experiment measured the lack of parallelism of measurements made on opposite sides of a mountain, looking at astronomical targets to measure G.

Surveying close to a large mountain mass has an error due to the mass of the mountains, of importance near the Andes and the Himalaya.

Answer 2

You aren't noticably pulled by large objects because the force of gravity is equal to G*m1*m2/D2 where G is the universal gravitational constant (6.67*10-11N*m2/kg2) 1, m1 and m2 are the masses of the two objects (in this case you and the building), and D is the distance between the centers of gravity of the two objects. So, if you were standing 10 meters (about 30 feet) away from the center of gravity of a building that weighs 10,000 kilograms (about 22,500 pounds) and you weigh 75 kilograms (about 170 pounds), the gravitational attraction between you and the building would be 5.0025*10-7kilograms (just over 50 millionths of a gram) 1N*m2/kg2 is a unit of measurement
