PendulumIt is not affected by
(1) Mass of pendulum bob (2) Angle of release Note that the period of pendulum is indeed affected by the angle of release, but by a very small amount. Therefore, to minimize this, we normally release the pendulum with an angle less than 10 deg such that it wont affect the period of pendulum. This means whenever we talk about angle of release for pendulum, we assume it is a small angle. Also, note that the formula stated above is only valid for small angle of release. These factors can be analyzed with the applet below. Detailed steps to analyze each factor are found below the applet.
