Welcome to the Physics 1 Applet Page
To view these applets, you will need a Java 1.1 enabled browser. You can
find out which version your browser supports by the applet below. If
you have a version below 1.1, you will need to upgrade your browser.

with running these applets on platforms such as Macintosh and Linux/Unix, though there
have not been too many problems running these on a Windows platform.
Space Time Physics Lab
The Space Time Physics Lab applet demonstrates some physical effects of
Einstein's Special Relativity, such as Lorentz contraction, time dilation,
a light clock, Michelson-Morley experiment, Barn & Ladder paradox, and Car
LRC Circuit Lab
The LRC Circuit Lab applet displays a circuit with a inductor, resistor,
and capacitor in series with an alternating current, showing the effects
of resonance and complex impedance.
The Electric Field applet allows the user to set up a distribution of
charges, upon which the applet will show the electric potential, electric
field lines, and equipotential lines. In addition, the electric force
will be observed through real time interaction of charges.
The Moving Charge applet shows the field of a moving charge, and how it
is concentrated in directions perpendicular to the motion. It also shows
how information only propogates at the speed of light, and shows how the
accelerating charge emits radiation by the compression of electric field
lines, which produces an electromagnetic wave.
The Magnetic Field applet shows interactions between moving charges. It
shows with a system of two wires why magnetic fields must exist in order
for the postulates of relativity and charge invariance to be consistent
with one another.
The Inductance applet shows how EMF is induced in a loop by changing
the magnetic flux through the loop. The different ways to change the
flux includes changing the current in a nearby wire, changing a uniform
background magnetic field, rotating the loop, moving the loop through
a non-uniform field, and changing the size of the loop.
