# Period of a Simple Pendulum Example Problem

A simple pendulum is a mass hanging from a massless string of length L swinging from a central pivot point. As the mass is pulled out at a small angle theta and released, the mass will swing back and forth in periodic motion. This example problem will show how to calculate the period of a simple pendulum.

The period of a simple pendulum refers to the time it takes for the mass to complete one complete cycle of its swinging motion. This time can be calculated using the formula

where
T = period
L = length of the pendulum
g = acceleration due to gravity
