 Title: Elastic bouncing ball Post by: ahmedelshfie on May 27, 2010, 07:18:10 pm This applet is Elastic bouncing ballCreated by prof Hwang Modified by AhmedOriginal project Elastic bouncing ball (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=421.0)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.
