Here's a breakdown:
* Mass: The more mass an object has, the stronger its gravitational pull.
* Distance: The closer two objects are, the stronger the gravitational force between them.
Here are some examples of what gravity exerts:
* Keeps us on the ground: The Earth's gravity pulls us towards its center, keeping us from floating off into space.
* Causes the tides: The moon's gravity pulls on the Earth's oceans, causing the tides to rise and fall.
* Keeps the planets in orbit: The sun's gravity keeps the planets in our solar system in their orbits.
* Forms stars and planets: Gravity pulls together clouds of gas and dust, eventually forming stars and planets.
Key points:
* Gravity is a fundamental force of nature.
* It's always present, even if we don't always feel it.
* Gravity plays a crucial role in the universe, shaping everything from the smallest particles to the largest galaxies.
