Here's a little more about gravity:

* It's a force of attraction between any two objects with mass. The more massive an object is, the stronger its gravitational pull. Since Earth is very massive, it exerts a strong gravitational pull on everything around it.

* Gravity keeps us on the ground, pulls the moon around the Earth, and holds the Earth in orbit around the sun.

* It's not just a force pulling things down. Gravity actually acts between any two objects, but we only feel it strongly from Earth because it's so big.
