ClarityHow to use this tool
- Enter first mass, second mass, center-to-center distance.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| First mass | Numeric value. Unit: kg. Must be greater than zero. | 1000 |
| Second mass | Numeric value. Unit: kg. Must be greater than zero. | 1000 |
| Center-to-center distance | Numeric value. Unit: m. Must be greater than zero. | 2 |
Result for these sample inputs
0.00001668575 N
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Force = Gm1m2/r²; G = 6.67430 × 10⁻¹¹ m³/(kg·s²).
Using first mass = 1000 kg, second mass = 1000 kg, center-to-center distance = 2 m, the result is 0.00001668575 N. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
An idealized educational model using the stated SI units. Real systems may need additional forces, losses or experimental measurements. Not a safety or equipment specification.
