Gravitational Force Calculator

Discover the invisible forces that govern our universe. Calculate the gravitational attraction between any two objects using Newton's law of universal gravitation.

Input Parameters
Enter the masses and distance, or choose from preset celestial bodies

💡 Earth-Moon average distance: 3.844 × 10⁸ m

Gravitational Force Result
The attractive force between the two objects

Enter values above to calculate the gravitational force

Newton's Law of Universal Gravitation
F = G × (m₁ × m₂) / r²

F = Gravitational force (Newtons)

G = Gravitational constant (6.674 × 10⁻¹¹ m³/kg⋅s²)

m₁, m₂ = Masses of the objects (kg)

r = Distance between centers (m)

Did you know? This fundamental law explains everything from why apples fall to Earth to how planets orbit the Sun. The gravitational force between you and Earth right now is your weight!

Fun fact: The gravitational force between Earth and Moon creates our tides, while the Sun's gravity keeps our entire solar system in perfect cosmic dance.

Understanding Gravitational Force

Gravitational force is one of the four fundamental forces in nature, responsible for keeping planets in orbit, holding galaxies together, and making objects fall to Earth. This universal force acts between any two objects with mass, no matter how small or large.

Newton's law of universal gravitation states that every particle attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. Use our calculator to explore this fundamental cosmic force!
