Here's why:
* Mass and Gravity: Gravity is a fundamental force of nature that arises from the mass of objects. The more massive an object, the stronger its gravitational pull.
* Attraction: Gravity always acts as an attractive force. This means that it pulls objects together, never pushes them apart.
* Newton's Law of Universal Gravitation: This law describes the strength of the gravitational force between two objects. It states that the force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
So, while you might think of gravity as a "force" that pulls, it's actually more accurate to think of it as a curvature in the fabric of spacetime caused by the presence of mass. This curvature influences the paths of objects, making them "fall" towards each other.
