In the course of the past two weeks, the Mile-nator was built. We knew that if we wanted to win, we would have the find the most suitable but the most functional materials. Not only does using lightweight materials useful, it is very fragile too. There were many times when our car broke. One incident was when someone accidentally stepped on it. Although heartbroken, it gave us an idea that would furthermore save our car. For our wheels, we decided to use plastic CD’s because it seemed like the most reasonable choice. The body of out car is made up of cardboard and two bottle caps which act as front wheels. The force that acts upon our car is the rubber band, which is different compared to everyone else.
Newton’s first law, inertia, applies to our car because it states that an object will remain at rest or continue moving unless an outside force acts upon it. In our case, the outside force is the rubber band. The vehicle stays at rest when we don’t uncoil the rubber band, and is moving after we uncoil it and let it go. Unlike the other balloon-powered vehicles, once we let out vehicle go it will run on the four wheels given and not release air. Because of the uncoiling, it really depends on if the rubber band is coiled enough that it goes at a fast enough speed or distance, or it becomes tangled.
Newton’s second law, acceleration, states that an object with more mass demands a greater force to move it. By using lightweight and recyclable materials, the Mile-nator isn’t as heavy. If it isn’t heavy, it doesn’t require as much force needed on a heavy object. If we used a heavy object, not only would it decrease the speed and distance of our car because its weighing it down but it will also push the vehicle down altogether. This is why we chose not to use and metal our heavy objects or any wooden pieces.
Action and reaction is Newton’s third law, and it requires that when an action is taken there should be an opposite reaction. In the Mile-nator’s case, the action is the coiling of the rubber band and the reaction is the wheels turning as we release it. Without the rubber band acting as the force, the car wouldn’t move at all. It wouldn’t even pass the starting line.
Although I don’t want to admit, I think that the A.N.T 2000 is the losing car. I think so because their wheels weren’t ideal, as they used cardboard and it doesn’t react as well on hard surface. Even if the car has an air balloon mechanism, it doesn’t give the car too much of a boost. The car often loses control too. Another major loser was us because we had problems with the rubber band in the first place. Overall, I think that this was an interesting project. It tested our minds and it challenged us to think outside the box.
