Compute the small-angle period of a simple pendulum from its length and gravity with T = 2π√(L/g).
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Pendulum period | T = 2π·√(L/g) | Huygens 1673; small-angle approx |
| Gravity | default g = 9.80665 m/s² | Standard gravity ISO 80000-3 |
