Re: After PWD cars comes...

I had a 77 Vette, it was always good fun in the snow... after we upped the pony power it would do a lot of that on the pavement too... eventually it did blow a tire, roll over and play dead... if someone tells you that you can't roll a Corvette, they lie! :wall:

Re: Handling your PWD addiction.

My wife and I have a great marriage and today is our 8 year anniversary. Yet you're here, making all these post... does she think you are ordering her a present on-line? Maybe doing some on-line banking, transferring some money around so you can take her some place nice? I know, tell her you think ...

Have you considered Pixie Dust? :scratching:

Re: Why light weight bodies? Yes Im ready for heavy physics..

How about speed is constant rather that down track speed? That was the only difference I was looking at... would the path not be slightly longer with the side to side motion? Wouldn't that actually take away from the down track speed?

Sweet... sign me up I'll take 2... see if they will give you a commission first for selling them here. :drool:

Re: Why light weight bodies? Yes Im ready for heavy physics..

Let's go with a flaw in the track, then we can assume the alignment is dead on and the car started perfectly straight... that would take a few more variables out of the equation. As for the books and dust :rofl: I was wondering which one of us was going to break down first and actually look somethin...

Re: Why light weight bodies? Yes Im ready for heavy physics..

The cat was not driving the ice cream truck, it was just running into the side of it... how dumb do you think I am... Petrified cats can't drive. :wall: This might help get over this small hurdle, since I do agree with most every thing else if the conditions had a certain amount of reality injected ...

Longer path yes, but where is this rotational energy going... it can't just disappear.

Re: Why light weight bodies? Yes Im ready for heavy physics..

I agree we need to be on the same page here, hence the 'stab' at simple physics rather than heavy physics. As for the change of direction not form... my stance was that the change in direction was not changing the form of the energy as happens when the friction changes the energy into heat. Maybe we...

Re: Why light weight bodies? Yes Im ready for heavy physics..

Here is our next job, take these two points: Force=Mass*Acceleration and Work (energy)=Force*distance! Further losses are probable because the collisions are not 100% elastic. would repeatedly changing the direction of body rotation consume additional kinetic energy, such that the car would oscillat...

Re: Why light weight bodies? Yes Im ready for heavy physics..

However, doesn't a rotating object have stored energy? One would think, however... you are not really changing anything but the vector... you are going straight, now your going right, now your going left, now your going... your rotation is noting more than another direction... and if there is no fr...

Re: Why light weight bodies? Yes Im ready for heavy physics..

Stan's back! Now I can stop quoting him and he can explain all this physics stuff... :D

Oh and since there is no suspension on the cars, more than one wheel will have to go off the track, even if only one wheel hits the bump.

Re: Why light weight bodies? Yes Im ready for heavy physics..

Ya, I gave the cat thing a thumbs down too but it is what spurred on the pool table. LOL My mind runs amuck sometimes. Change in direction is vague... it could encompass pitch, roll, yaw... depends if you hit a joint in the track and the car bounce up on both sides... if a wheel runs over some [junk...

Re: Why light weight bodies? Yes Im ready for heavy physics..

I'm aware of the problems with the ball on the pool table, I was just trying to simplify things... my other thought actually had to do with a petrified cat in a hypothetical 2 dimensional universe deflecting off an ice cream truck in LEO round what seemed to only be a photograph of the earth which h...

Yup, if the air is still where the track is set up and the cars are traveling at 12 MPH it is the same as if the cars stood still and the wind blew over them at 12 MPH.
