What Is a Gravity Formula Calculator?
A Gravity Formula Calculator is an online tool that calculates the gravitational force between two objects using Newton’s Law of Universal Gravitation.
The formula used is:
F = G × (m₁ × m₂) / r²
Where:
- F = Gravitational Force (Newtons)
- G = Universal Gravitational Constant (6.67430 × 10⁻¹¹ N·m²/kg²)
- m₁ = Mass of the first object (kg)
- m₂ = Mass of the second object (kg)
- r = Distance between the centers of the two objects (meters)
The calculator automatically performs the calculation and provides an accurate result without requiring manual computations.

Understanding the Gravity Formula
Newton’s Law of Universal Gravitation states that every object attracts every other object in the universe.
The strength of this attraction depends on:
- The masses of the objects
- The distance between them
Larger masses create stronger gravitational forces, while greater distances reduce gravitational attraction.
This relationship follows an inverse-square law, meaning if the distance doubles, the gravitational force becomes four times weaker.
Example Calculation
Suppose:
Mass 1 = 500 kg
Mass 2 = 300 kg
Distance = 20 meters
Using the formula:
F = G × (500 × 300) / (20²)
The Gravity Formula Calculator automatically computes the gravitational force without requiring manual calculations.
