2、 of skill in the use of simple machines & the understanding of Newtons Laws & Energy. There will be individual winners in the following categories: SPEED: Fastest legal Jet Car to cover 3 linear meters wins. DISTANCE: The car that travels the longest linear distance using a legal Jet Car.GRADINGThis

Look over chapters 3, 4, 5, and 7 in your textbook to decide which principles apply. Motion, forces, fri
5、ction, Newtons Laws, energy transformation, and simple machines are a few of the many concepts that come into play. Be sure to consider these principles when designing and building your JET CAR. In your lab write-up you will be asked to explain how these factors influenced your design, even if by ac
6、cident.Before you begin, read the rules carefully and think about what type of car you would like to build. The first attempt at designing the car will probably not be the one you end up competing with. So allow yourself plenty of time to design and begin building the car.I strongly encourage each o
7、f you to strive for excellence! Do not be discouraged if you need to make several modifications to your original design. The continuous process of refining a design is what science and engineering are all about! In the past, some builders have made enough modifications that they had to build a secon
8、d car. Test your car several times throughout the building process. I also recommend waiting until you have a successful design before devoting a lot of time to your cars cosmetic appearance. The next few pages illustrate some of the cars basic components as well as different design ideas. Pick and
9、choose from these ideas or come up with your own! Remember, you can decide how to focus your efforts speed & distance or both. JET CAR Write-upDue Date: _Your responses to the following topics should be typed in complete sentences. You should refer to your notes and the textbook. This is a cumulativ
10、e look at many of the physics concepts we will or have covered this semester. Your task is to make your explanations as clear and to-the-point as possible so there will be no doubt in my mind that you know what youre talking about. I expect you to use the physics vocabulary we have discussed in clas
11、s rather than vague, everyday language. Feel free to conference with me before turning in your final write-up. I would be happy to offer feedback on your rough draft so you can be confident that you are getting your ideas across. This is your opportunity to SHOW ME what you have learned!TOPIC #1: Ne
12、wtons LawsState each of Newtons Laws and explain how each law applies to the motion of your jet car. Consider the forces involved during the beginning, middle, and end of your cars run.TOPIC #2: Conservation of EnergyDescribe how energy was conserved or perhaps lost during your cars run. How were po
13、tential and kinetic energy involved? Which forms of energy were involved and how? (See your notes or textbook for the different forms of energy.)TOPIC #3: Simple MachinesDescribe any simple machines that make up your jet car. What class of lever was used, if any? Discuss the ideal mechanical advanta
14、ge of each simple machine (calculations optional). Did you use the machines to multiply force or distance? How did these concepts influence the design you chose?TOPIC #4: SummarySummarize what you learned through the process of building and racing your jet car. Be sure to discuss any problems you encountered and how you solved them. What were your cars strengths and weaknesses? What changes would you make to your car in the future and why?
