F = G * (m1 * m2) / r²

Where:

* F is the force of gravity between two objects

* G is the gravitational constant (approximately 6.674 × 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

Explanation:

* The law states that every particle in the Universe attracts every other particle with a force that is:

* Proportional to the product of their masses: The more massive the objects, the stronger the gravitational attraction.

* Inversely proportional to the square of the distance between their centers: The farther apart the objects are, the weaker the gravitational attraction.

Key points to remember:

* This law applies to all objects with mass, no matter how small or large.

* The force of gravity is always attractive, meaning it pulls objects towards each other.

* The gravitational constant (G) is a fundamental constant of nature and has the same value everywhere in the Universe.

Examples of the law in action:

* The Earth's gravity pulls you towards its center, keeping you on the ground.

* The Moon is held in orbit around the Earth by gravity.

* The Sun's gravity holds the planets in their orbits.
