* Gravity is a force of attraction: Every object in the universe exerts a gravitational force on every other object. This force is directly proportional to the mass of the objects and inversely proportional to the square of the distance between them.

* Mutual attraction: When two objects are close enough, the gravitational force between them becomes significant. This force pulls them towards each other.

* Examples:

* The Earth and the Moon: Gravity keeps the Moon orbiting the Earth.

* The Sun and the planets: Gravity holds the planets in their orbits around the Sun.

* Falling objects: The Earth's gravity pulls objects towards its surface, causing them to fall.

Think of it like this: Imagine you have two magnets, and you bring their poles closer together. The magnets pull towards each other because of the magnetic force. Gravity works in a similar way, but instead of magnetic poles, it's the mass of objects that attracts them.
