Gravity is the force that pulls two objects together. What many people do not understand is that while the earth is pulling us toward it, we are pulling the earth to us with the same force. The difference is that the earth is so massive compared to us that we don’t notice the force with which we pull the earth. Gravity allows the orbit of bodies around others in our solar system (like the moon around the earth), and is what ultimately keeps us on the earth.
Gravity is the attraction matter has to other matter. It is one of the four fundamental forces in the universe, and the weakest.
