PHYIC CALCULATOR
Newton’s Law of Gravitation Calculator
A precise tool.
What is the Newton’s Law of Gravitation Calculator & How does it work?
Newton’s Law of Gravitation describes the gravitational force between two masses. The law states that every particle attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
F = G frac{m_1 m_2}{r^2}
F = Gravitational force, G = Gravitational constant (6.67430 × 10⁻¹¹ N⋅m²/kg²), m₁ = Mass of the first object, m₂ = Mass of the second object, r = Distance between the centers of the two masses.
This formula is fundamental in understanding how objects interact gravitationally at a distance. It applies to all objects with mass, from subatomic particles to planets and galaxies.

Frequently Asked Questions
What is Newton’s Law of Gravitation?
Newton’s Law of 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.
How do I use this calculator?
Enter the mass of the first object, the mass of the second object, and the distance between their centers. The calculator will compute the gravitational force using Newton’s Law.
What is the gravitational constant G?
The gravitational constant G is approximately 6.67430 × 10⁻¹¹ N⋅m²/kg², used in calculating gravitational forces between masses.
Can I use this calculator for celestial bodies?
Yes, you can use this calculator to estimate the gravitational force between planets, moons, or other celestial bodies by inputting their respective masses and average distances.
What units should I use for mass and distance?
For mass, use kilograms (kg), and for distance, use meters (m). The calculator will then output the force in newtons (N).
How does changing the distance affect the gravitational force?
Increasing the distance between two masses decreases the gravitational force significantly, as it is inversely proportional to the square of the distance.
Is this calculator suitable for everyday objects?
While the law applies universally, the forces calculated for everyday objects are typically too small to be noticeable without sensitive equipment.
