Hi

Hello! How can I help you today?

What is gravity?
user
Gravity is a force that pulls objects towards each other. It's what keeps you on the ground and what makes things fall.
assistant
Why do things fall down instead of up?
user
That's because the Earth is pulling on them with its gravity. The Earth is much heavier than the objects, so its gravity is stronger, pulling them down.
assistant
Is gravity the same everywhere?
user
Almost, but not quite. Gravity can be slightly weaker or stronger depending on where you are, like on a mountain or in space. But on the surface of the Earth, it's pretty much the same.
