F = Gm₁m₂/r²; G = 6.67430 × 10⁻¹¹ N·m²/kg²
Point or non-overlapping spherical masses. Positive distance.
How to use this calculator
- Identify the quantities and convert them to the units shown.
- Apply the formula first, then compare with the substitution and result.
- Check the assumptions and whether the order of magnitude makes sense.
Levels are approximate topic groupings, not a complete curriculum for every country. Numerical results are rounded and may lose precision for extreme or nearly singular inputs.
