Pendulum Calculator

Calculate the period and frequency of a simple pendulum using T = 2π√(L/g). Enter the pendulum length.

How to Use the Pendulum Calculator

  1. Enter the length of the pendulum (from pivot to center of mass) in meters.
  2. Click Calculate to find the period and frequency.
  3. The result assumes small-angle oscillation.

Fórmula

T = 2π × √(L/g), where T is period (s), L is length (m), g ≈ 9.807 m/s². Frequency f = 1/T.

Perguntas Frequentes

Does mass affect the period?
No, the period of a simple pendulum depends only on its length and gravitational acceleration, not on mass.
Is this accurate for large swings?
This formula is accurate for small angles (< 15°). For large swings, the period is slightly longer.
Is this calculator free?
Yes, all OhMyCalc calculators are completely free.
