Formula
F = G × m₁ × m₂ / r², where G = 6.674×10⁻¹¹ N·m²/kg², m₁ and m₂ are masses (kg), r is distance (m).
Domande Frequenti
What is the gravitational constant?
G = 6.674×10⁻¹¹ N·m²/kg², a fundamental constant that governs the strength of gravitational attraction.
Does distance matter a lot?
Yes, gravitational force decreases with the square of the distance — doubling the distance reduces force by 4×.
