Gravitational Force Calculator
What is a Gravitational Force Calculator?
A Gravitational Force Calculator is a tool used to determine the gravitational force between two masses based on Newton’s Law of Universal Gravitation. The force is measured in Newtons (N).
Why Use a Gravitational Force Calculator?
- Helps in astronomy, physics, and engineering to study the interaction of objects.
- Essential for understanding planetary motion, satellite orbits, and free-fall motion.
- Used in designing space missions, bridges, and structures where gravity plays a role.
How to Calculate Gravitational Force?
The formula is:

Where:
- F = Gravitational force (N)
- G = Gravitational constant (6.674 × 10⁻¹¹ N·m²/kg²)
- m₁, m₂ = Masses of the objects (kg)
- r = Distance between the objects (m)
Example Calculation:
If m₁ = 1000 kg, m₂ = 500 kg, and r = 10 m,

When to Use a Gravitational Force Calculator?
- Calculating the force between planets, moons, and satellites.
- Studying free-fall and weight variations at different locations.
- Designing space missions and satellite orbits.
- Understanding tidal effects and large-scale gravitational interactions.
