Here's a little more about gravity:
* It's always attractive: Gravity always pulls objects towards each other, never pushes them away.
* It depends on mass: The more massive an object is, the stronger its gravitational pull. This is why the Earth pulls us towards it, but we don't feel the pull of a small object like a book.
* It depends on distance: The closer two objects are, the stronger the gravitational force between them. This is why we feel the Earth's gravity more strongly when we're standing on its surface than when we're in space.
Let me know if you have any other questions about gravity! 😊
