Simulating Dynamics using Java 3D

I am trying to create a prototype to simulate dynamics using Java 3D for education purposes. The prototype is supposed to simulate the basics of dynamics with runtime values.

Being pretty new to Java 3D , I ve been able to find the basics of 3D object creation , and basic transformations. When it comes to implementing dynamics in Java 3D, i could not find any materials to help in this regard. Could anyone help with some sources or references on this regard......
