Gravitational Force Proportionality Calculator
Gravitational force proportionality is a fundamental concept in physics, describing the attractive force between two objects. Our calculator simplifies the complex formula, making it easy to compute forces quickly and accurately.
- Enter the masses of the two objects in kilograms (kg).
- Enter the distance between the two objects in meters (m).
- Click ‘Calculate’ to find the gravitational force.
The formula for gravitational force is:
F = G * (m1 * m2) / r^2
Where:
- F is the force of gravity,
- G is the gravitational constant (6.67430(15)×10⁻¹¹ m³ kg⁻¹ s⁻²),
- m1 and m2 are the masses of the two objects, and
- r is the distance between the centers of the two objects.
| Object 1 | Object 2 | Distance (m) | Force (N) |
|---|---|---|---|
| Earth (5.972 × 10^24 kg) | Moon (7.348 × 10^22 kg) | 3.844 × 10^8 | 1.98 × 10^20 |
- Always use consistent units for the best results.
- For very large or small masses and distances, consider using scientific notation.
What is the gravitational constant (G)?
The gravitational constant is the strength of gravitational interaction between two objects. Its value is approximately 6.67430(15)×10⁻¹¹ m³ kg⁻¹ s⁻².
