Example: a marble and a bowling ball. Even though the other is much heavier, when dropped, they will accelerate similarly. Why? Due to their shape, they have similar wind resistance, regardless of their size difference. Because the force causing their acceleration towards the ground is constant and equal(gravity). well the shape thing is pretty much right, but the bowling ball would still drag more through the air because of it's size. The reason two objects of different mass and similar shape fall at the at the same acceleration (9.81 m/s[squared]) is different. The force on the bowling ball is much greater, which is why it weighs more - remember weight is a measure of force, not necessarily mass. However, because the bowling ball is of much greater mass, it takes a proportionally greater force to accelerate it at 9.81 m/s(squared). So, when the two objects hit the ground, the bowling ball will be at the same velocity as the marble, but it's kinetic energy (M x V[squared]) will be greater. I also saw some comment on weight/mass robbing hp??? I dont see mass in the equation Torque x RPM / 5250. Regarding lateral acceleration and top speed, Increased mass will ONLY make it take longer to get there. What we're concerned with is the point that the force of wind resistance equals the force the engine can supply - this does not change with mass.

LOL
Look at us, we're in a CAR forum discussing Newton's Laws...
Stay tuned for tomorrows discussion: Does E=mc(squared)? LOL

a marble will hit the ground before a bowling ball because there is less wind resistance on the marble
 ...therefore... the bowling ball will hit the ground after the marble

Not to nitpick, just noticed this after I'd already clicked reply, but it's 5252, not 5250... right?

5252????
Havn't heard that before.... but hey it's not nitpicking, dude I want to know if I'm wrong.... Anyway, serriously let me know (anyone) what the correct constant is. Oh yeah SkylineUSA , Einstien is du shit man, fo real

I got around to making the aero drag calculator. Just input frontal area, drag coefficient, vehicle weight and speed and it spits out how much horsepower is needed.
http://www.davewin.com/tech/horsepower_calc.shtml This is all based on the little write up I did earlier in this thread. Let me know what you guys think.

Excellent scripting, and awesome site, I might add. My only complaint about your site? No links to AF  .You should talk to Igor about some kind of partnership. Maybe one of the tech forums or something.
