Here's a little more about gravity:
* What is it? Gravity is a force of attraction between any two objects with mass. The more mass an object has, the stronger its gravitational pull.
* Earth's gravity: Earth has a large mass, so it exerts a strong gravitational pull on objects near its surface. This is why things fall to the ground when you drop them.
* Not just Earth: Gravity exists everywhere in the universe. It's what holds the moon in orbit around the Earth and the planets in orbit around the sun.
