Formula
Variables
- m1 — Mass 1 (kg)
- m2 — Mass 2 (kg)
- r — Distance (m)
Worked example
With mass 1 = 5.972e24 kg, mass 2 = 7.348e22 kg, distance = 3.844e8 m, the calculator gives gravitational force ≈ 1.9821 × 10²⁰ N.
Frequently asked questions
What is the newton's law of gravitation calculator used for?
Calculate the gravitational force between two masses. It helps with questions such as “gravity between earth and moon”, “attraction between masses”, “calculate newton's law of gravitation”.
What is the formula for the newton's law of gravitation calculation?
Gravitational force (N) = GCONST × m1 × m2 / (r × r). Here m1 is mass 1 (kg), m2 is mass 2 (kg), r is distance (m).
What inputs do I need for the newton's law of gravitation calculator?
You need mass 1 in kg, mass 2 in kg, distance in m. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the newton's law of gravitation calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the newton's law of gravitation result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
