Gravitational Force Calculator
Calculate gravitational force between two masses using Newton's Law of Universal Gravitation. Compute gravity on different planets and celestial bodies.
What is Gravitational Force Calculator?
This gravitational force calculator applies F = G(m₁m₂)/r² to compute the attractive force between two masses separated by a distance. Also shows how your weight would differ on the Moon, Mars, Jupiter, and other celestial bodies.
How to Use This Calculator
- Enter your Mass 1, Mass 2, Distance in the input fields provided
- Results are computed instantly as you enter or modify values — no need to click a button
- Review the computed output showing your gravitational force results with a detailed breakdown
- Verify the result against your textbook or lab data and note the units used in the output
How Gravitational Force Calculator is Calculated
This calculator uses the formula: F = G × m₁ × m₂ / r². Where G = 6.674×10⁻¹¹ N·m²/kg² ; m₁,m₂ = Masses ; r = Distance between centers. Newton's law of universal gravitation. Escape velocity = √(2GM/r). All calculations run entirely in your browser — no data is transmitted to any server.
Frequently Asked Questions
What is the gravitational constant G?
G = 6.674 × 10⁻¹¹ N⋅m²/kg². It is a universal constant that determines the strength of gravity. Despite being a fundamental force, gravity is extremely weak — two 1 kg masses 1 m apart attract with only 66.7 piconewtons.
How much would I weigh on Mars?
Mars gravity is 3.72 m/s² vs Earth's 9.81. You weigh 38% of your Earth weight on Mars. A 70 kg person weighs 686.7 N on Earth but only 260.4 N on Mars.
