8 Amazing Javascript Experiments of Physic and Gravity Simulation


In this list I have gathered 8 examples/experiments that apply physics and gravity to demonstrate the power of Javascript. Few years back, all of these experiments must be done using Java or Flash, I don't think we can implement this using Javascript because of the standard and browsers.

A lot of stunning examples in this list, personally, I like the Cloth Simulation a lot, I just can't believe it's built with Javascript.

  • Cloth Simulation

    This amazing javascript experiment demonstrate the power of javascript. Few years back, this wasn't achievable and I think you only can do it with Java or flash. Pretty impressive and the creator uses javascript physics library called Processing.
  • Random Arboretum

    Yet another physic experiment that uses the javascript physic library called Processing. Everytime you click on it, it will generate a radom branch. Look at the way it shakes and move, it's really nice.
  • Box2DJS

    Box2D is an open source physics engine written primarily for games. As the name suggests, Box2D is a purely 2D engine. BOX2DJS is a Javascript port of BOX2D.
  • Ball Pool

    Start by shaking the browser, then create new balls (click on empty space), move some others (drag) and reset the screen (double click). Stunning gravity and physic demonstration!
  • Google Gravity

    What will happen when we put gravity on every single elements in Google's homepage?
  • Wavy Scrollbars

    A very creative use of scrollbar to simulate wave effect. Best view with chrome, firefox is a bit laggy.
  • Waterfall

    Balls falling on an hidden random terrain. This experiment is using physic simulation trought the library box2djs.
  • physicSketch

    When you draw something on a canvas, it starts moving under the Newtonian law.

FYI, Processing is a programming language based on Java, not Javascript. The first two examples are nice physics demos, but are examples of Processing. Reply

Really cool experiments. You should have tried to build some game out of these :P Reply

The first two examples use java applets not javascript, unfortunately ... Reply

The cloth one is awesome, but the google gravity made me literally laughing! It's so funny to see google "fail" although it never will :-) Reply

that's all cool & great js simulations, thank you very much for sharing.

Can you give me favor to <a href="http://www.javascriptbank.com/submit/">share this post</a> on my JavaScript library?

Awaiting your response. Thank Reply

I built an open source JavaScript Physics Library. It can be used together with Scriptaculous effects and can draw lines, and that all without HTML5. have a look https://github.com/ChristophPacher/JavaScript-Physics-Library

I just created high quality version of javascript cloth simulation. I'd say it's very cool. Look there:

The google gravity script taken from here (http://code.google.com/p/gravityscript/) doesn't appear to work probably on the Safari browser. /yet Mr Doob's google gravity script works fine on Safari. Does anyone know why this might be???
