Car Physics

The search for a new car exposed me to the world of car physics. I remembered when I was overwhelmed by all those numbers listed in a car web site. What does this all these numbers mean? My natural curiosity leads me to explore them. It turns out car physics is intellectually more interesting than I think. So I somewhat go beyond what I intended to.

The main purpose of these pages is to help you understand the phsyics that underlies the car numbers you find in most car web sites and car magazines. It might greatly improve your understanding of cars. Hence, you can make a better decision on buying cars. You might also learn something to improve your driving. I hope you enjoy these pages. ^^

Good news to the loyal readers of this page. My friend Stephen Chi Yung Ng joined me to write some of the pages. He is currently doing Physics PhD at Stanford University. He should be able to keep my physics honest. Let's all welcome him! =)

Oh, if you are interested in helping me to finish this page and you live in San Francisco Bay Area, please email me at I need a computer graphics person and a a math/physics type who can run some integration (e.g. MATLAB). Thanks! :)
