What is Newton's law of universal gravitation?
Newton's law of universal gravitation states that every two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of the distance between them: F = G × m1 × m2 / r².
What can this gravitational force calculator find?
This calculator can find gravitational force, either mass, or the distance between two objects. Select one value to calculate, then enter the other three known values.
How do I calculate gravitational force between two objects?
Enter both masses and the distance between them, then leave force selected as the calculated value. The calculator applies F = G × m1 × m2 / r² and converts the result into your selected force unit.
How do I calculate distance from gravitational force?
Select distance as the output, then enter gravitational force and both masses. The calculator rearranges the formula to r = √(G × m1 × m2 / F).
Can I use different units for mass, force, and distance?
Yes. You can choose separate units for both masses, the distance, and the force result. The calculator converts values internally before solving the equation.
What is the gravitational constant G?
The gravitational constant G is the proportionality constant used in Newton's gravitation formula. This calculator uses G = 6.67430 × 10^-11 N·m²/kg².
