In this video I go over five example problems for calculating the period, frequency, length and acceleration due to gravity for a simple pendulum.

A pendulum is a mass suspended from a string that is attached to pivot point. There is no friction so that the pendulum can swing freely. When displaced from the equilibrium position and released the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for the pendulum to complete one complete cycle is called the period. The frequency of the pendulum is the number of cycles the pendulum completes in one second.
