Calcolatrice Forza Gravitazionale — Formula
## Newton's Law of Universal Gravitation
Every mass attracts every other mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
### Formula
**F = G * m1 * m2 / r²**
where G = 6.6743 x 10^-11 N·m²/kg² is the gravitational constant.

Esempio Risolto
Weight of a 70 kg person on Earth's surface (Earth mass = 5.972e24 kg, radius = 6,371,000 m).
- F = G * m1 * m2 / r²
- F = 6.6743e-11 * 5.972e24 * 70 / (6.371e6)²
- F = 6.6743e-11 * 4.1804e26 / 4.059e13
- F ≈ 687 N (close to 70 * 9.81 = 686.7 N)
