Find the period of a simple pendulum from its length and the local gravitational acceleration using the small-angle approximation.
输入摆长 L 与重力加速度 g,求周期。
| Item | Standard / Source | Key Point |
|---|---|---|
| Simple pendulum period | Small-angle approximation (classic); T = 2*pi*sqrt(L/g) | Valid for small angles (below ~10 degrees) |
