The Pendulum
Part of the Mechanics section of Coddy's Physics journey. Lesson 83 of 97.
Pull a pendulum aside and the part of the weight along its path pulls it back toward the lowest point.
The part of the weight along the path, mg sin θ, pulls the bob back toward the middle.
For small swings, up to about :
The mass of the bob is not in it.
Challenge
