Here's a bit more about gravity:

* Universal force: It's a fundamental force of nature that acts on everything with mass.

* Attraction: Gravity always attracts objects towards each other. The more mass an object has, the stronger its gravitational pull.

* Distance: The force of gravity weakens as the distance between objects increases.

* Earth's gravity: The reason we stay on the ground and objects fall when dropped is because of Earth's gravitational pull.

* Other celestial bodies: Gravity also keeps the Moon orbiting the Earth, and the planets orbiting the Sun.
