Physics assignment?

Question

okay, so for my physics assignment i need to chose some sort of transportation... airplane, bicycle, etc etc.
i can also do a wheel, or something like that. anyways, i have to find "the physics connection" and make a 2-3 minute report on it.
i was wondering if you guys knew any good sites where i could find out what the physics behind any of those objects are?
i dont need you to explain to me, i just want some sites if you know any.
thanks!!
