Pendulum Period Calculator
Use this calculator to determine the oscillation period of a simple pendulum based on its length and the gravitational acceleration.
What this calculator is doing
A simple pendulum exhibits periodic motion, and its period \( T \), the time it takes for one complete oscillation, is given by the formula:
\[ T = 2\pi \sqrt{\frac{L}{g}} \]
Where:
\( T \) = Period (seconds, s)
\( L \) = Length of the pendulum (meters, m)
\( g \) = Acceleration due to gravity (meters per second squared, m/s²)
This formula assumes small-angle oscillations and an idealized simple pendulum. The calculator takes the length and optional gravitational acceleration as input (default is Earth’s gravity: 9.80665 m/s²).
