Here's why:
* Gravity is a fundamental force of nature that attracts any two objects with mass. The more mass an object has, the stronger its gravitational pull.
* Newton's Law of Universal Gravitation describes this force mathematically, showing that the force of gravity is proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between their centers.
So, whether it's the apple falling to the ground or the Earth orbiting the Sun, gravity is the force responsible for this attraction between objects with mass.
