1.9821e+20Newtons (N)* Using Universal Gravitational Constant G ≈ 6.6743 × 10⁻¹¹ N⋅m²/kg²
Newton's Law of Universal Gravitation
Newton's law states that every particle attracts every other particle in the universe with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
F = G × (m₁ × m₂) / r²
- F (Force): Measured in Newtons (N).
- G (Gravitational Constant): Approximately 6.6743 × 10⁻¹¹ N⋅m²/kg².
- m₁ & m₂: The masses of the two objects, measured in kilograms (kg).
- r: The distance between the centers of the two objects, measured in meters (m).
