This java applet illustrates relations between displacement, velocity and acceleration for one dimensional motion.
<center><table BORDER CELLPADDING=5 ><tr ALIGN=CENTER><td>green curve</td><td>blue curve</td><td>red curve</td></tr>
<tr ALIGN=CENTER><td>displacement</td><td>velocity</td><td>acceleration</td></tr>
<tr ALIGN=CENTER><td>x</td><td>v=dx/dt</td><td>a=dv/dt</td></tr></table></center>

<ol><li>Try to move the mouse within the windows.</li><li>Try to click and drag the mouse within the window</li><dd>==> You can change the acceleration a</dd><li>Try to click the start button and look at the motion of a round ball.</li></ol>

THIS IS BULLSHIT MAN
WTH  CANNOT GET THIS TO WORK
AN ERROR DENOTED THAT SEVERAL VIRTUAL MACHINES ARE CONFLICTING AT THE SAME TIME.
I UNINSTALLED JAVA AND REINSTALLED IT BUT STILL CANNOT WORK.
WTH DAMN THIS
