Ooh, gravity is like a big hug from the Earth!

You know how when you give your favorite toy or stuffed animal a big hug? You squeeze them tight, right?

Gravity is like the Earth giving the whole world a big hug. It pulls everything towards itself, so you don't float away into space. It's what keeps you on the ground and what makes things fall down instead of up.

Imagine you have a ball, and you throw it up in the air. What happens? It comes back down to the ground, right? That's because the Earth is giving it a big hug with its gravity!
