earlier today my brother was watching a playoff game on espn while i was eating lunch. during a commercial he flipped up a channel and ended up watching drag racing. i never really watched a race before because it didnt really look interesting but it actually is because some races are determined by a few miliseconds and some races are determined by a couple of second becasue the cars are all designed differently. this remined me a lot about the mousetrap cars we had to make. the car everyone wants has a low moment of inertia because the race only lasts for a couple of seconds so the wheels start spinning easily. the equation is I=mr2 (that means squared). also, you would want wheels with some traction so that it makes your wheels spin faster initially. i dont know where they stationed the mike but i did get a chance to experience the dopler effect.
i learned that drag racing is kind of fun to watch when you dont have anything to do :)
