Gravitational Attraction
Calculate Newtonian attraction for point masses or nonoverlapping spherical masses.
How it works
Calculate Newtonian attraction for point masses or nonoverlapping spherical masses.
Using this calculator
Enter first mass (kg), second mass (kg), center-to-center distance (m). F = Gm₁m₂/r²; G = 6.67430 × 10⁻¹¹.

Are my entries saved?
No. Calculator inputs remain in the current page and are cleared when you reload or leave. The tools do not upload your entries.
Why are results rounded?
The display is rounded for readability. Calculations use unrounded intermediate values. An estimate should not be interpreted as an exact measurement.
