Simple Pendulum Period of Oscillation Explanation Question
Three masses hang from strings of negligible mass attached at a fixed point, all in identical environments .
Pendulum 1 consists of a mass of 2 kg suspended on a 1 m long string. Pendulum 2 consists of a mass of 4 kg
suspended on a 1 m long string. Pendulum 3 consists of a mass of 2 kg suspended on a 0.5 m long string.
Question: Calculate and compare the period of each pendulum, then rank the periods from longest to
shortest.
