Title: Pendulum
Post by: Fu-Kwun Hwang on June 13, 2010, 04:57:58 pm
Pendulum
This is a simulation of a pendulum formed by a bob of fixed mass that is suspended from a rod (of neglilible mass) under the action of gravity.
When the bob is displaced from the stable equilibrium state (the lower vertical position with zero initial velocity), gravitational forces tend to recover this position.
In the absence of friction, the movement observed is called simple harmonic motion.
