Gravitational Force Calculator

Calculate gravitational force using Newton's law F = Gm₁m₂/r². Enter two masses and their distance.

How to Use the Gravitational Force Calculator

  1. Enter the first mass in kilograms.
  2. Enter the second mass in kilograms.
  3. Enter the distance between the centers of the two masses.

使用例

計算式

F = G × m₁ × m₂ / r², where G = 6.674×10⁻¹¹ N·m²/kg², m₁ and m₂ are masses (kg), r is distance (m).

よくある質問

What is the gravitational constant?
G = 6.674×10⁻¹¹ N·m²/kg², a fundamental constant that governs the strength of gravitational attraction.
Does distance matter a lot?
Yes, gravitational force decreases with the square of the distance — doubling the distance reduces force by 4×.
Is this calculator free?
Yes, all OhMyCalc calculators are completely free.
