 Title: Elastic bouncing ball Post by: Fu-Kwun Hwang on February 25, 2007, 12:57:16 pm An elastic ball bouncing off the walls and another hard semi-circle object.Collision between two objects is simulated with a invisible spring.$\vec{F}=-k*\Delta \vec{s}$, where $\Delta\vec{s}$ is the displacement of the spring from it's original length. You can adjust the spring constant k to change its elastic property.Press pause and adjust the velocity of the ball with mouse (or drag it off center) to watch interesting motion.-*- Title: EJS source file download button error: file does not exists! Post by: lookang on July 09, 2007, 10:58:22 pm sorry but i can't get it ;D Title: Re: Elastic bouncing ball Post by: Fu-Kwun Hwang on July 10, 2007, 03:45:16 am You should be able to download it now. Title: Re: Elastic bouncing ball Post by: Engineero on October 31, 2009, 04:47:39 am could you but java code for this simulation pleaseand I'm not that good in open source is there any source for thishttp://faculty.ifmo.ru/butikov/Projects/Falling_bodies.html Title: Re: Elastic bouncing ball Post by: lookang on October 31, 2009, 11:22:59 am for source codes by other authors u should ask them directly.  alternatives similar applet that i madeEjs Open Source Creative Commons Attribute Projectile motion Java Applet http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=745.0has the source codes for sharing under license attribution.u could do a search for "projectile motion" in this forum and u will find a couple more :)enjoy! Title: Re: Elastic bouncing ball Post by: Fu-Kwun Hwang on October 31, 2009, 10:34:34 pm Here is a EJS version of the simulation similar to the one at http://faculty.ifmo.ru/butikov/Projects/Falling_bodies.htmlThe force for the particle is assumed to be $\vec{F}=-b\vec{V}-\vec{g}$.You can adjust parameter b and restitution coefficient with slider.The id slider control which particle will be modified when x,y,z,vx,vy,vz are adjusted with slider.You will find "size effect" when b>0. i.e. smaller particle slow down faster.

Title: Elastic bouncing ball Post by: Femida on March 27, 2015, 01:37:32 am I congratulate, your idea simply excellent Title: Re: Elastic bouncing ball Post by: lookang on December 23, 2015, 09:30:56 am i have a JavaScript version herehttp://iwant2study.org/ospsg/index.php/interactive-resources/physics/02-newtonian-mechanics/01-kinematics/37-kinematics-in-y-directionselect dropdown menu "free fall and rebounce"(https://lh4.googleusercontent.com/-o1a8H9RVMMQ/U0SBSYyWhzI/AAAAAAAAgNg/NcFU1wEkoCU/s640/blogger-image-1827329758.jpg)enjoy!
