Here are some key points about gravity:
* Universal: Every object in the universe exerts a gravitational force on every other object.
* Attractive: Gravity always pulls objects towards each other, never pushes them apart.
* Dependent on mass and distance: The strength of the gravitational force depends on the masses of the objects involved and the distance between them. Larger masses and shorter distances result in stronger gravitational forces.
Gravity is what keeps us on the ground, holds the Earth in orbit around the Sun, and causes the formation of stars and planets.
