Surface Gravitational Acceleration

Formula

g = G M / r²

  • *G* = 6.674e-11 N m² kg⁻²
  • *M* = body mass
  • *r* = body radius

    • Divide by 9.80665 m/s² to express in multiples of Earth's standard gravity.

    计算示例

    Confirm Earth's surface gravity.

    1. g = G M / r²
    2. G M = 6.674e-11 × 5.972e24 = 3.986e14
    3. r² = (6.371e6)² = 4.059e13
    4. g = 3.986e14 / 4.059e13 ≈ 9.82 m/s²
