Explain Like I'm 5

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

You know how when you're playing outside and you throw a ball up in the air, it comes back down to the ground? That's because the Earth is giving it a big hug! The Earth is pulling everything towards it, including you and your ball.

Imagine you're holding a balloon and you let go. What happens? It floats up in the air, right? But then what? It comes back down to the ground! That's because the Earth is giving it a big hug, pulling it back down.

Gravity is like the Earth's hug, and it's what keeps us and everything else on the ground!
