Q How do I stop things from rolling off into infinity, or pendulums from 
swinging forever? 
A ODE models a universe with frictionless hinges and no rolling friction, so 
problems like those are fairly common. The solution is to apply a force to 
simulate rolling friction or aerodynamic drag. 

The faq is your friend :-)
