Introduction
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.
