Gravity is a fundamental force of nature that attracts any two objects with mass. The more massive an object, the stronger its gravitational pull.

Here's why you feel pulled towards the Earth:

* Earth's Mass: The Earth has a huge amount of mass, which creates a strong gravitational field.

* Your Mass: You have mass, even though it's much smaller than Earth's.

* Mutual Attraction: Earth's gravitational field attracts you, and your gravitational field attracts the Earth, although your pull on Earth is negligible.

This mutual attraction is what keeps you grounded and is responsible for many phenomena like the tides, the orbits of planets and moons, and even the formation of stars and galaxies.
