Understanding Newton's Law of Universal Gravitation

What is Newton's Law of Universal Gravitation?

Newton's Law of Universal Gravitation states that every particle attracts every other particle in the universe 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. This law, published by Sir Isaac Newton in 1687, explains the motion of planets, the trajectory of projectiles, and the behavior of objects on Earth.

How to Use This Calculator

1. Enter Mass Values: Input the masses of the two objects. You can use different units (kg, g, lbs, Earth masses, Solar masses) - the calculator will convert them automatically.
2. Set the Distance: Enter the distance between the centers of the two masses. Choose appropriate units (meters, kilometers, AU, etc.).
3. Calculate: Click the "Calculate Gravitational Force" button or use celestial presets for quick calculations.
4. Interpret Results: View the gravitational force in Newtons along with equivalent comparisons and detailed breakdown.
5. Use Presets: Try the celestial body presets to see real-world examples of gravitational forces.
