Newton's Law of Gravitation Calculator

Computes the gravitational attraction between two masses a distance apart, plus the gravitational field and potential energy.

Notes

  • F = G·m₁m₂/r² with G = 6.674×10⁻¹¹ N·m²/kg². Gravity is extremely weak unless at least one mass is astronomical.
  • The defaults are the Earth, the Moon and their separation.
