Java Applets for Reaction Time Measurements :

1)      http://www.phy.ntnu.edu.tw/java/Reaction/reactionTime.html. This site is a good exercise to measure reaction time when you are driving!  It is also a good example for accelerated motion.

2)      http://javascript.internet.com/games/react-button.html.  Play this on the screen and record your reaction times as many as your instructor requires.  Do not need to copy the script to your computer!!!

3)      http://www.kean.edu/~biology/timeit.html. In this reaction time measurement applet, a different aspect of your reaction time is measured!  You need to start the program at a button by clicking on it, then move the mouse to another one to stop it.

Java Applets for Astronomy/Physics:

1)      http://www.arachnoid.com/sky/.  This applet contains some Astronomy, heat pump, and an ideal gas simulation.  Ideal gas and heat pump are impressive.  Also appropriate for high school level.

2)      http://www2.biglobe.ne.jp/~norimari/e-sciencenori.html.  Some of the demo’s in this site are more advanced.  One of the best I have seen so far. PHYS 221,220

3)      http://www.lightlink.com/sergey/java/. This site contains some optics, magnetic field and electric circuits applets.

4)      http://webphysics.ph.msstate.edu/jc/library/16-5/index.html.  Electric field lines are drawn for a given set of charges.  It is OK applet, however,  it does not produce ,on its own,  proportional number of lines!

5)      http://www.phy.ntnu.edu.tw/java/emField/emField.html. This applet shows the path of a charged particle in a E and B field.  Good for PHYS 221 class.

6)      http://www3.adnc.com/~topquark/fun/JAVA/electmag/electmag.html. Another advanced applet showing the motion of a charged particle in electromagnetic field. PHYS 221

7)      http://www.cco.caltech.edu/~phys1/java/phys1/EField/EField.html. This is a very good applet to show filed lines as well as equipotential lines.  It does places correctly the number of lines!(five star). PHYS 221, PHYS 212

8)      http://ostc.physics.uiowa.edu/~wkchan/EM/PROGRAMS/POLARIZATION/. This demo shows polarization.  PHYS 221, PHYS212
