Below you will find some simulations that are useful for demonstrating and experimenting with physics phenonema. Some were developed by me (mem2), some are created by my former Professor Andrew Duffy from BU, and other are from various sites that I have come across over the years (such as, Andrew Duffy at BU and NTNU Virtual Lab). Click on an image and Enjoy.
And I would like to thank Andrew Duffy and Nick Gross from BU ITOP for introducing me to EJS.
NOTE 1: You must have JAVA RUNTIME ENVIRONMENT installed to run these simulations.

NOTE 2: If you are having trouble using these on Internet Explorer (IE) you should first download and use Firefox or Google Chrome. If you really have to stay with IE and are having problems, it is because IE likes to rename Java files to ZIP files when saving/opening them. To fix this, save the file by Right-click Save As ... IMPORTANT ... and add ".jar" to the end of the file name when saving. This should force IE NOT to rename the file to .zip. You should then be able to open it by double clicking on the file on your computer, assuming you have Java installed.

NOTE 3: Since Apple thinks they are better than everyone else, they disallow the use of Java on iPads ... which unfortunately means Apple will not allow you to run sims like these and Phet on iPads. Forshame Apple, forshame!
