Gravity is a type of force. Did you know that gravity pulls all objects to the ground with the same amount of force? If you would drop two objects from the same height and at the same time, then they will hit the ground at the same time. On Earth air resistance can slow some objects more than others. On Earth gravity pulls all objects to the center of the Earth. Did you know that on the moon, gravity is not as strong? It is not as strong because the moon does not have as much mass. You would weigh less on the moon compared to Earth. If there was not gravity, things would not fall to the Earth. Gravity keeps the Earth going around the sun, keeps you on the ground, and causes objects that you throw into the air to come back to the ground.
