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 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

This formula describes the force of attraction between any two objects with mass. It's a fundamental law of physics that explains why objects fall to the ground and why planets orbit stars.
