<h1>The 2D Pendulum</h1>
<p>
<font size=+1>A</font>lthough the pendulum is a simple object that might be expected
to have uninteresting
behavior, in fact its behavior can be rich and complex. In this lab we will examine
methods for determining
the motion of a two-dimensional pendulum, one which is confined to swing in a plane. In this section of the site we
begin with a
simple model of pendulum motion and systematically improve the approximations.
</p>
<p>
This section uses a Java applet to illustrate key points and aid in the visualization of the problem at hand. The applet is designed to help students explore different parameter regimes of the two-dimensional pendulum. In addition, this gives students immediate feedback on the validity of different approximation schemes. To activate the applet simply click on the control bar in the the lower frame. For help on the use of the applet <a href=help.html>check here</a>.
