can weight be an advantage?
have you ever had to build a toy car in school and race them down the wood board to see wich one is faster? and you realize that more weight going down hill makes it go faster.
my ? is this. if i'm on the highway racing and its on a slight downhill, will my weight help rather than go against me?

Re: can weight be an advantage?
of course it will help, your logic is perfect their young, and i remember those good old days building the wood cars with dad, sigh, weight is also advantagious when it comes to traction and highspeed control, the vr4's weight is one reason it is so poised and stable at maximum velocity.

Sorry, but the weight makes no difference when it comes to going downhill. There is not enough drag on the cars to make any difference against the force of gravity with something that weights thousands of pounds.
In those old grade school efforts, the weight was low enough that air resistance affected how well gravity accelerated the car. The amount on a real car is negligable. Then you also have to remember 9.2 meters/second squared is the best you could be accelerating without help if you go over a cliff. Clearly, the grade isn't close to that so the acceleration offered by gravity is even smaller. To bad though - it would be nice to have some advantage besides the stability.

Re: can weight be an advantage?
The added weight will help you in the snow along with narrower tires.

drop a brick and a bouncy ball at the same time? Ever notice anything? They both hit the ground at the same time. It doesnt matter what your weight is, gravity will accelerate you downard at the same rate. The thing that affects gravities pull is aerodynamics.

Re: can weight be an advantage?
anyone have any written info on how aerodynamic our cars are and how much it affects speed compared to other cars?
and your right i just picked up a pencil and a magazine dropped them and they landed at the same time. i then got a cd and the pencil and droped them at the same time and the pencil fell first. then i turned the cd sideways so that it would cut through air faster and they droped at the same time.

Re: can weight be an advantage?
the drag coefficient of the 3000 is .33 I found this spec. on http://www.3si.org/

Isn't that only inside a vacuum? LOL Don't mean to get into physics and crap but an object falling inside a vacuum doesn't have air resistance which which makes the acceleration due to gravity 9.8 m/s^2. Well, I know a penny and a feather hit the ground at the same time inside a vacuum.

Don't get me fired up about physics - I love that stuff
 Anyone who wants a quick refresher http://www.glenbrook.k12.il.us/gbssc...ss/BBoard.html Great stuff

HAHA, I'm staying out of this one, I missed all of Physics class due to the cute girl next to me.

ooo man I love physics.... I have it right now in school....I guess I'm a bit of nerd
 If you drop two objects form a height thats not very high they'll hit the ground at the same time. But the heavier and more massive one is going to hit with a lot more force. If you got hit on the head with a pencil it wouldn't hurt very much but a bowling ball would, even though they were going the same speed. That's why the heavier cars, back in school, went faster because they had more force to overcome air resistance. But when going at higher speeds aerodynamics is much more important than weight or mass.
