Calculate the gravitational force between two masses using Newton's law of universal gravitation F = Gm₁m₂/r². Determine the attractive force between any two objects with mass.
Enter your values below
First mass (e.g., Earth: 5.97 × 10²⁴ kg)
Second mass (e.g., Moon: 7.35 × 10²² kg)
Distance between centers of mass
How this calculator works
Newton's law of universal gravitation states that every mass attracts every other mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
