Simple pendulum period
Estimate the period of a simple pendulum for small angular displacements.
Method and scope
T = 2π√(L/g), using standard gravity.
Use simple pendulum period for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Pivot-to-bob length — m, cm, ft
SOURCE AND LIMITS
Assumptions: The bob is approximated as a point mass on a massless string. Maximum angular displacement is small (about 15° or less). Standard gravity 9.80665 m/s² is used.
Limitations: Larger swing angles increase the true period compared with this small-angle approximation.
