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

9)      http://www.nwlink.com/~klbarrus/antenna/antenna.htm. This is advanced applet.  It may be good for electrical engineering students.  ENGINEERING,ADVANCED  PHYSICS

10)  http://www.cco.caltech.edu/~phys1/java/phys1/MovingCharge/MovingCharge.html. This is also advance, it shows the electric field lines of a moving charge.  You can control the motion of the charge. PHYS 221

11)  http://home.a-city.de/walter.fendt/phe/acceleration.htm. This is about accelerated motion. It includes a sketch of the motion along with graphs and numerical displays.  MECHANICS , PHYS 220 or PHYS 211

12)  http://home.a-city.de/walter.fendt/phe/pendulum.htm.  This is an excellent simulation for energy, force on the pendulum bob, velocity and displacement of the pendulum.

13)  http://home.a-city.de/walter.fendt/phe/phe.htm.  Excellent simulations by Walter Fendt about electricity, mechanics, thermodynamics, optics, atomic model, modern, nuclear, one in an relativity and more.  One of the best and most complete demo set I have ever seen.  PHYS 221, PHYS 220, PHYS 211, PHYS 211
