Simulations Written in JavaScript

The "canvas" tag in HTML5 enables you to set up an area on a web page on which you can draw diagrams, images, text, etc, using JavaScript commands.

So I've taught myself JavaScript and associated web page design to construct a number of interactive simulations, mainly physics ones.

I have constructed each simulation as a single "stand-alone" HTML file with the JavaScript code incorporated within the file. The simulations will work on all modern browsers and can be played off-line. The file sizes are very small, only round about 10KB.

I have also made a start to create "Teacher Notes" to accompany selected simulations. This is a 'work in progress'.

Click here to DOWNLOAD a package of eleven simulations (and one Teachers' Notes document) in zip format (84KB, October 2021 version). The simulations are:

• A Simple Punnett Square
• Vertical Spring SHM
• Radioactive Decay
• Longitudinal Waves
• Standing Waves
• Equilibrium on a Beam
• Series LCR - Circuit Calculator
• Series LCR - Linking Voltage Graphs with Phasor Diagram
• Projectile Motion
• Simple Pendulum with Variable Initial Angle
• Random Walker
