The Flap over Roof Flaps

Why Roof Flaps? Roof flaps (the invention of which I detail in my book The Physics of NASCAR) help keep cars on the ground.  This is necessary because of Bernoulli’s law, which says basically that: Faster-moving air exerts less pressure. Slower-moving air exerts more pressure. A wing develops lift because the […]

Keeping Racecars on the Racetrack

Ryan Newman escaped NASCAR sanctions for his comments immediately after being discharged from the infield care center at Talladega.

“They can build safer racecars, they can build safer walls, but they can’t get their heads out of their asses far enough to keep them on the race track and that’s pretty disappointing, and I wanted to make sure I get that point across,” he said. “You all can figure out who ‘they’ is.”

A Quick Post on Why Cars Go Airborne

A quick post for my friend, @TheOrangeCone that I’ll expand on later (I have theater tickets tonight!)

@TheOrangeCone asked why Kurt Busch went airborne in the Talladega crash. The answer is the same for all the cars that end up in the air: when a car rotates (so that its side or its back is leading instead of its front), it looks an awful lot like an airplane wing — a shape that is optimized to generate lift.
