Universal gravitationF = Gm₁m₂ / r²Equal and opposite forces

Gravitational force2.67 × 10⁻⁸ N

Center distance5.00 m

Mass product10,000 kg²

Force ratio1.00× baseline

Both masses feel the same force in opposite directions. Doubling either mass doubles force; doubling distance reduces force to one quarter.

Look at the variables in F = Gm₁m₂/r².

G = 6.67430 × 10⁻¹¹ N·m²/kg²
