An elastic ball bouncing off the walls and another hard semi-circle object.
Collision between two objects is simulated with a invisible spring.
, where 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.

sorry but i can't get it

[Fu-Kwun Hwang]

You should be able to download it now.

could you but java code for this simulation please
and I'm not that good in open source is there any source for this
http://faculty.ifmo.ru/butikov/Projects/Falling_bodies.html

[lookang]

for source codes by other authors u should ask them directly. 

alternatives similar applet that i made
Ejs Open Source Creative Commons Attribute Projectile motion Java Applet
http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=745.0
has 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!

Here is a EJS version of the simulation similar to the one at http://faculty.ifmo.ru/butikov/Projects/Falling_bodies.html

The force for the particle is assumed to be .
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.

I congratulate, your idea simply excellent
