Material Detail

This applet does a good job representing coupled oscillators with the 2 masses
and springs. Also the graphs help to explain and show the relationships of
coupled oscillators.

The applet demonstration of two springs connected by another spring helped to
show how one spring is inversely affected by the action of another. The display
of the sine waves of the springs helped in understanding the inverse
relationship if the spring action is not fully visualized initially.

The interaction of the two springs is a very good effect. The ability to
manipulate the initial positions of the springs gives the ability to perceive
different perspectives. As the values get higher however, the ability to
understand what is occuring becomes blurry. The contortions of the springs
gives a visual aid in understanding the idea of conservation of the energy that
is important for students to not only visualize, but utilize as well. The only
thing I found frustrating was the deletion of the current set of results when
the graph reached the end of the view box. Other than that, this sight is very
good and I would recommend it for those who are trying to gain an understanding
of oscillation.

A very good demonstration of the topic. There are quite a few similar applets available, and this one is above average.
