F = G * (m1 * m2) / r²

Where:

* F is the force of gravity between two objects

* G is the gravitational constant, approximately 6.674 x 10⁻¹¹ N⋅m²/kg²

* m1 is the mass of the first object

* m2 is the mass of the second object

* r is the distance between the centers of the two objects

Explanation:

* The force of gravity is directly proportional to the product of the masses of the two objects. This means that the larger the masses, the stronger the force of gravity between them.

* The force of gravity is inversely proportional to the square of the distance between the centers of the two objects. This means that the farther apart the objects are, the weaker the force of gravity between them.

Key Points:

* This equation describes the force of attraction between any two objects with mass in the universe.

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

* The gravitational constant (G) is a universal constant that applies to all objects in the universe.

This equation is fundamental to understanding many phenomena in our universe, including the motion of planets, stars, and galaxies.
