What to enter
| Input | Meaning and units |
|---|---|
| Central mass (kg) | Enter central mass in kg; use the same basis as the other measurements. |
| Distance from center (m) | Enter distance from center in m; use the same basis as the other measurements. |
Understanding your result
Read Gravitational acceleration (m/s²) in the units and model stated on this page. The formula g=6.67430e-11*mass/(r*r) defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
