The Gravitational Field Strength Calculator will calculate:

- Gravitational field strength on the surface of a planet of mass M, which has a radius R.
- Gravitational field strength at height h from the surface of a planet of mass M, which has a radius R.

The gravitational field strength of a planet on its surface is m/s^{2} |

The gravitational field strength at a certain height from the surface of a planet is m/s^{2} |

g^{0} = G × M/R^{2}g ^{0} = × /()^{2}g ^{0} = /g ^{0} = |

Gravitational field strength at a certain height from the surface of a planet calculation |

g = G × M/(R + h)^{2}g = × /( + )^{2}g = /()^{2}g = /g = |

Gravitational Field Strength Calculator Input Values |

Mass of the planet (M) kg |

Radius of planet (R) m |

Height of the object from the surface of planet (h) m |

Gravitational Constant (G) N∙m^{2}/kg^{2} |

Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each gravitational field strength calculation, the Gravitational Field Strength Calculator will automatically calculate the results and update the Physics formula elements with each element of the gravitational field strength calculation. You can then email or print this gravitational field strength calculation as required for later use.
