What to enter
| Input | Meaning and units |
|---|---|
| Initial angular velocity (rad/s) | Enter initial angular velocity in rad/s; use the same basis as the other measurements. |
| Final angular velocity (rad/s) | Enter final angular velocity in rad/s; use the same basis as the other measurements. |
| Elapsed time (s) | Enter elapsed time in s; use the same basis as the other measurements. |
Understanding your result
Read Angular acceleration (rad/s²) in the units and model stated on this page. The formula alpha=(w2-w1)/t 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.
