Gravitational Force Calculator – Instantly Calculate Force Between Two Masses

Welcome to our powerful Gravitational Force Calculator – an essential tool for students, scientists, engineers, and curious minds alike! Based on Newton’s Law of Universal Gravitation, this calculator helps you determine the attractive force between any two objects with mass, separated by a known distance.

🔍 What is Gravitational Force?

Gravitational force is the mutual attraction between two bodies due to their masses. It’s the force that keeps planets in orbit, causes tides, and makes objects fall to the ground. It is defined by the formula:


    F = G * (m₁ * m₂) / r²

Where:

F = Gravitational Force (Newtons)
G = Gravitational Constant = 6.67430 × 10⁻¹¹ N⋅m²/kg²
m₁, m₂ = Masses of two objects (kg)
r = Distance between centers of the two masses (meters)

⚙️ How to Use the Gravitational Force Calculator?

Enter the mass of the first object (m₁) in kilograms.
Enter the mass of the second object (m₂) in kilograms.
Input the distance (r) between the two objects in meters.
Click on “Calculate” to get the gravitational force in Newtons (N).

❓ Frequently Asked Questions (FAQs)

1. Is gravitational force always attractive?

Yes, gravitational force is always attractive. It pulls masses toward each other, unlike electrical forces which can repel.

2. Can I calculate gravity on other planets using this tool?

Absolutely! You can use the known mass of a planet and an object, and the radius of the planet to calculate the gravitational force.

3. Does this calculator work for any two objects?

Yes, as long as you know their masses and the distance between their centers, you can compute the force – whether it’s between moons, asteroids, or everyday objects.

4. Is this calculator based on real scientific principles?

Yes. It’s based on Newton’s Law of Universal Gravitation, one of the foundational laws in classical physics.

5. Can I use this for educational demonstrations?

Definitely. Teachers and students frequently use this tool for labs, homework help, and classroom experiments.
