Well if you want to nick pick, you are wrong,

The Continental United States is the area of the United States of America comprised of the 48 states located south of Canada and north of Mexico (known as the "lower 48 states"), the US capital of Washington, D.C., and the state of Alaska north of Canada. The Continental United States does not include the state of Hawaii located on a group of islands in the Pacific Ocean or any other territories under the control of the United States. Some references erroneously mistake the Continental United States for the Contiguous United States (which consists simply of the lower 48 states)


Was jsut a comparison FFS

Here's a random trivia/fun fact: if you want to nitpick, you shouldn't say "nick pick"

Theoretically, the faster you move, the slower time elapses in reference to the moving object. This only really works on a larger scale though. For example, when an astronaut returns from the moon, he or she is actually a few seconds or minutes (can't remember) younger than if he or she would havestayed on earth. This also relates to the concept that at the speed of light, time stops, according to the object traveling at the speed of light.

Not always true, depends on the Cd. Very important.

Always true. The coefficient of drag if a function of AREA! Very important.


Better dust off that fluid dynamics book.

Just cuz area appears in the function doesn't mean it's the only thing it depends on. Intuitively, do you think it would take the same amount of force to overcome air resistance @ any speed for a brick shaped object or a teardrop shaped object, with the same frontal areas?

Cd and frontal area tell the whole story, neither one tells it alone, I'm pretty sure.

Didn't mean to start an argument. Some guy on the speed demon team just told me about the plate thing. Theres alot that goes into figuring that out. Like tempature, elevation, baro pressure. The list goes on. Fluid dynamics is really cool tho. Really want to study it but I'm poor and already paying on student loans.
