Space Calculator

Advanced tools for orbital mechanics and celestial body calculations. Explore the physics that govern our universe.

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.
