Every particle of matter in the Universe attracts every other particle with a force that is:
* Proportional to the product of their masses. This means that the more massive the objects, the stronger the gravitational force between them.
* Inversely proportional to the square of the distance between their centers. This means that the farther apart the objects are, the weaker the gravitational force between them.
Mathematically, this can be expressed as:
```
F = G * (m1 * m2) / r^2
```
Where:
* F is the force of gravity
* G is the gravitational constant (approximately 6.674 x 10^-11 N m^2/kg^2)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
This law is one of the fundamental laws of physics and explains a wide range of phenomena, including:
* The orbits of planets around the sun
* The tides on Earth
* The acceleration due to gravity near the Earth's surface
* The formation of stars and galaxies
