Simulation can help us visualize the physics model. You will find hundreds of physics related java simulations (download available for registered user).
  • * Tell me. I may not get it, I'm sure to forget it.
  • * Show me. I may get it, I'll remember it for a little while.
  • * Have me do it. I'll understand it, it may stick for a while.
Registered user will be able to get files for offline use.

No New Posts Request for physics Simulations rss
If you can not find physics related simulations you want. Post it here, describe the requirement and the design of the simulation in detail. And we will try to create one for you for free! We need to know the purpose for the simulation and the targeted user. Normally, we will start to create it within one week as soon as we have enough information to create the simulation.
  • * Have me teach it. I'll really know it, I'll remeber it for a long time.
  • * And, anyone that has ever written programs to model something has learned...
  • * Have me program it. Guru. Can you say eternity!

No New Posts Physlet builder (Create your own simulation) rss
Do you believe it! You can create your own simulations without writing a line of code. You just need to provide your design as property values and the simulation will be created and send to your email account. (So only registered user can access the simulation builder interface). Let us will show you how to create your own simulation (with step by step flash movie.) URL=Physlet Simulation Builder

Easy Java Simulations (2001- )
No New Posts Information and Download rss
Easy Java Simulations (Ejs) is a software tool designed for the creation of computer simulations. It is designed for sicence teacher (not for professional programmer) What user need to do is supply information about science model (define variable, provide initial condition- initial value for variables , giving evolution condition -how variable change with time or constrains between variables) , Ejs will create java applet/ html page for your simulation. Please check out EJS wiki download for latest version
