All objects on earth are pulled toward the ground by gravity. If everything is being pulled by gravity, why don't we notice smaller things, like people or chairs, pulling on each other?

Question

1. small objects don't have gravity
2. gravity only works on objects touching the ground
3. the pull of gravity between small objects is too weak to feel

Answer 1

The correct answer is:

3. The pull of gravity between small objects is too weak to feel.

While all objects with mass exert a gravitational force on each other, the strength of that force is dependent on the mass of the objects and the distance between them. Since people, chairs, and other small objects have relatively small masses in comparison to larger objects like the Earth, the gravitational attraction between them is extremely weak and not noticeable in everyday situations.
