F = G * (m1 * m2) / r^2

where:

* F is the force of gravity between two objects

* G is the gravitational constant, approximately 6.674 × 10^-11 m^3 kg^-1 s^-2

* 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:

* Gravitational Force: This equation describes the attractive force between any two objects with mass. The force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

* Gravitational Constant (G): This constant represents the strength of the gravitational force. It is a fundamental constant in physics.

* Mass (m1, m2): The larger the masses of the objects, the stronger the gravitational force between them.

* Distance (r): As the distance between the objects increases, the gravitational force between them decreases rapidly.

Key Points:

* The gravitational force is always attractive, pulling objects towards each other.

* The equation applies to all objects, regardless of their size or shape.

* The force of gravity is a fundamental force in the universe, responsible for keeping planets in orbit around stars, and for the formation of galaxies and other large-scale structures.
