Every particle of matter in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Here's a breakdown:
* Every particle attracts every other particle: This means gravity is a universal force that applies to all objects with mass.
* Proportional to the product of their masses: The more massive the objects, the stronger the gravitational force between them.
* Inversely proportional to the square of the distance between their centers: The farther apart the objects are, the weaker the gravitational force between them. The force decreases rapidly as the distance increases.
This law is represented mathematically by the following equation:
F = G * (m1 * m2) / r²
Where:
* F is the force of gravity
* G is the gravitational constant (approximately 6.674 x 10⁻¹¹ N⋅m²/kg²)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
This law explains why objects fall to the ground, why the planets orbit the sun, and why galaxies hold together. It's a fundamental law of physics that has had a profound impact on our understanding of the universe.
