Surface Gravity vs Body Mass
Fórmula
## 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.
Ejemplo Resuelto
Confirm Earth's surface gravity.
- 01g = G M / r²
- 02G M = 6.674e-11 × 5.972e24 = 3.986e14
- 03r² = (6.371e6)² = 4.059e13
- 04g = 3.986e14 / 4.059e13 ≈ 9.82 m/s²
Preguntas Frecuentes
Why does Mars have lower gravity than Earth?
Mars has about 11% of Earth's mass and 53% of its radius, giving about 38% of Earth's surface gravity.
Does this formula work above the surface?
Yes, replace r with the distance from the centre (body radius + altitude). Gravity decreases as 1/r².
What is standard gravity?
Standard gravity is defined as exactly 9.80665 m/s².
