The applet design by prof Hwang, modified by Ahmed.
Original applet at [url=http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=2065.0]Spring sets (study effect sue to spring constant and mass)[/url]

There are three springs in the simulation.
You can use id slider to select one of the spring,
then use K slider to change it's spring constant, m slider to change it's mass
The damping costant are the same :assume damping force \vec{F}=-b\vec{v}

I modified the plot graphic panel  to be together applet you just need to click on plot to watch graphic.
