Rubber Band Car- Wheel Placement and Center of Gravity?

[QUOTE="scottdave, post: 5922642, member: 618222"] Is the driving force the fan (spinning propeller)? If that is the case, then traction will not matter (and would be detrimental). If the CD "wheels" provide the driving force, then you will want some traction on the ones which provide the drive force. You could use some rubber bands around the rim of the CD to create some "tires", if that is allowed in your race. Here is a video which talks about some of the physics behind Pinewood Derby cars. Note that their driving force is gravity, but it probably would be worth you watching. Some of what he talks about can apply to the motion of your car. [MEDIA=youtube]-RjJtO51ykY[/MEDIA] [/QUOTE]
