thanks for putting together one cool, informative, helpful site!
on the page
2 * ((MaMb)/(Ma+Mb) * ((VbiVai) dot n) * n
what is (VbiVai)? It cant be a dot product. You cant just multiply
two vectors afaik. Should this be (Vbi - Vai) ??
and ditto for the next equation also.
thanks, and keep up the good work!

I think you are right, I have corrected the web page. Thank you very much
for pointing this out (and also for your kind comments about the site).

Physics Modelling for Game Programmers. This book uses DirectX and C++ and shows how to build a physics modelling framework. It includes theory about many of the maths and physics topics required to write games. The theory is kept as simple as possible, almost no calculus (a few differentials have sneaked in) and no quaternions. I think it could be potentially confusing that impulse is described as force and given the letter F. The edition I have seen has some strange printing on the collision response derivation, w is printed as ... and torque is printed as ~.
