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
