When we were told we had to make our car better, Em and I knew right away that we were going to improve our cars wheels. You see, our original plan was cutting small bouncy balls in half, and then super glueing them to the CDs on the outside for stabilty. The problem was the holes weren't exactly straight, thus made our car wobble back and fourth and our lateral distance being 3.9 ft. Now, to fix this problem we pitched the wheels completely. We made new ones. We cut out wooden squares, 1x1/4, and glued them onto the wheels. That was it. This made the car travel further, and straighter so I guess you could say we were pretty happy. A small difference can be a huge one.
time for 5 feet- 2.58 seconds
time total- 10.90 seconds
total distance- 29.00 feet
lateral distance- .40 feet

Our car traveled better, further, and straighter because of what we had changed. The wheels became sturdier with no wobbling back and forth. So without wobbling back and forth our car spent its time traveling straighter rather than turning. Before we fixed our mistakes, our car traveled 18 feet. Now, after making improvements, our car traveled 29 feet (it went farther but backed up).
