1. Spring-Mass System A physical model has been constructed
with instrumentation to provide data for position and velocity.
There is an extensive website including pages on derivation of
equations of motion, analysis, numerical simulation, comparison
with experimental data, and refinement of the model. Several
Java applets are also available for experimentation by the user.
Status: essentially complete
2. Pendulum System. A physical model has been constructed
with instrumentation to provide data for position and velocity.
There is a website with information similar to that for the spring-mass
system. Status: well-advanced but some work remains to be done
on the website.
3, Spring-Pendulum System. This is a combination of the
first two modules. Status: physical model is complete; the website
exists only in outline form.
4. Forced Linear Oscillator. The module deals with a
linear spring-mass system driven by a sinusoidal force. A physical
model has been constructed that dramatically shows the dependence
of the amplitude and phase of the response on the frequency of
the force. Instrumentation provides data on position and velocity.
Status: physical model is complete; the website has not been
started.
5. Vibrations of a tightly stretched string. This module
will deal with the wave equation. Status: physical model is under
construction; the website has not been started.
