I have to make a cardboard car for my Physics class, and I was wondering how many wheels I should have? Should I use three wheels, or four wheels? I can use more, BUT I can only use ONE rubber band to power the car, and that would be on the back wheels, and if I put on too much wheels, it would create more friction, and weight than needed.
Also what do you think about the size/ thickness for the wheels? I ran a couple of test, and I find out that smaller wheels are faster, but cover less grounds, and the larger wheels cover more ground, but has less speed, and how thick should the wheels be? We're running on a pretty straight surface.
What do you guys think?
Oh I forgot to tell you: IT MUST TRAVEL A MINIMUM OF OF 10 METERS, AND HAVE A SPEED FOR 10 M/S.
