323 - How does gravity keep us grounded on Earth?

Gravity is an invisible force that keeps us stuck to the Earth. Here's how it works:

The Earth is a big ball, and it has a lot of mass (or 'stuff' inside). This mass creates a strong pull that attracts everything around it, including us. When we stand on the Earth's surface, the Earth's gravity pulls us towards its center. That's why we don't float off into space.

Imagine you have a ball on a string, and you swing it around your head. The string keeps the ball attached to your hand. Gravity is like that string, but invisible. It keeps us attached to the Earth, so we stay on the ground and don't float away.

So, thanks to gravity, we can walk, run, and play on the Earth without floating off into space.
