Have you ever wondered why we don't float away? It's because of gravity! Gravity is a force that pulls everything towards the center of the Earth. That's why when you drop your pencil, it falls down and not up. Even the moon is affected by gravity, it keeps it circling around our Earth. Without gravity, we wouldn't be able to walk, run, or play. So next time you're jumping or playing catch, remember it's all thanks to gravity!
