can anyone please help or send me the classes for a physics engine directx i have been trying for the last 2 weeks but no hope

You are unlikely to get an answer to your question,

The problem is your focusing on the solution, and the domain problem. There are many solutions to a problem, they all vary depending on your needs.

What you need to do is learn the domain information about physics simulation, abstract the concepts(which are your classes). From that write an analysis of what features you need to simulate. From their you will be able to gather your class names.

if it helps, i posted in the forum a link to a free ebook that has a framework supporting physics. which may help you
