How's your math?

Actually, it doesn't say much of anything and is completely useless. :/ It's all speculation and hypothesis, no conclusion to be found. Basically, they were trying to test that the cars lost less energy at the bottom of the ramp due to friction compared to the top of it. They gathered some data, but its useless since it wasn't ever finished and doesn't support the hypothesis. All they have is the velocity of the cars and thats it, no weights or anything.

Looks like a half finished research project that a high school kid made... and not one that got a good grade either.

I am of the school of thought that says that the LEAST scientific method of coming up with a winner is the best.

Trying to read it made my head hurt!

OK here's my very first real contribution to the hobby. As a certified ase master technician and I did study as I build 1:1 scale racecars for a living I have more that just a basic understanding of physics on vehicles and I can tell you most definitely that yes aerodynamics and all that hoopla do play a roll in even hotwheels all though it is just like everything else its scaled down to a 64th so everything that effects a real car will erect a toy car just on a much smaller scale aerodynamic, weight. Rolling resistance, friction but all on a 64th scale. Don't believe me? Put two vertical stabilizers on each side of the rear of a car and slow down the tape it will stay straighter longer which means faster cuz no bumping side to side . I'd be more than willing to work with any of you on these ideas

Might have to try some of that out lugnutz! What kind of race cars do you build?

Road cars mainly stuff for scca and a few years ago I did the silver state classic. A bunch of street/strip drag cars basically if you want to go fast I'm the guy u talk to.

Cool. I like working on old cars. I have two 1962 Cadillac projects, on sedan and a convertible...hopefully to soon have it back on the road. Also drive a 72 GMC pickup as my daily. No racing but love old cars.

now driving a channelled and sectioned '33 ford 5 window coupe, 351w, aod, 411 - 9"...my 9th hot rod...... in the oven a '34 ford coupe cum convertible project, 19 different consecutive years of ford skins... '29 to '51 ford parts,[ no 1943-45 ] ....289, c4, 300 - 9" truly one of a kind...

Sounds nice. Last hotrod I built was 36 Chevy sedan currently working on a fiero gt swapping in a new cobalt 2.2turbo and six speed for my new track car.

Glad to see some more "gearheads" here, lugnutz86. I'm a VW/Audi 'parts guy'...but I've worked with several European car lines over the years. I began my career working for GM dealerships but ended up almost half of the GM dealerships around me close up( ), I do not regret that decision.

to drive...especially in the snow!
