UNIT 5 - ETHARA SCIENCE AND MATH In this unit you will learn about just a few of the Science and Math concepts related to Formula Ethara. As you have seen, Formula Ethara Cars race down the special 20 metre race track. The racing is where all the Science and Math really kick in! What you need: Microsoft PowerPoint Software The #EtharaAtHome Project Portfolio PowerPoint file. If you haven't downloaded it yet, CLICK HERE to find it Internet access to view website links A calculator Overview: Review all the research and investigation material below to learn more about some of the Science and Math concepts related to Formula Ethara Racing Complete the activities below and record your work in the Science and Math sections of your #EtharaAtHome Project Portfolio. Part 1 - Science in Formula Ethara Racing There is a lot of science involved with what happens on the Formula Ethara Race Track. Most of the science is about physics. Physics is a huge subject that looks at the motion of matter and how matter interacts with energy and forces. Here are just a few of the science topics related to Formula Car Racing Acceleration Thrust Friction Aerodynamics Speed Distance Research & Investigate Watch the video to learn more about how Formula Ethara racing works. Pay close attention to the facts and figures, maybe pause / play and take some notes of them. Video - Formula Ethara - Science of Racing Activity - Racing Facts, Figures and How it Works Having watched the above video, go to the Science and Math section of the #EtharaAtHome portfolio and complete the following two activities. If you haven't yet downloaded the Portfolio file, CLICK HERE to find it From memory, recall the facts and figures and add them to the table in your portfolio Use the headings provided in the Portfolio and explain how each of the science topics listed can affect a Formula Ethara Race. If you need help to understand the topics, click on the video links below to learn more: Forces Acceleration Thrust Aerodynamics Friction Research & Investigate - Physics & Sir Isaac Newton Physics is an important field of science. It is the study of the relationship of objects, forces, and energy. Physics explains gravity, and the way things move. Sir Isaac Newton defined the Laws of Motion. These same laws are the basis for all modern and complex Physics calculations. They are even used to work out how to send people to Mars. Your Mission - Conduct online research to learn more about Isaac Newton and his Laws of Motion so that you enough information to complete the activity below in your #EtharaAtHome Portfolio Activity - Sir Isaac Newton Facts Go to the Science and Math section of the #EtharaAtHome Portfolio and fill in the missing words to complete the story about Isaac Newton. Part 2 - Math in Formula Ethara Racing If you have watched the Formula Ethara Race video in Part 1 you will have seen how the race start is controlled by five lights each turning red and then, after a few seconds the lights go turn off / go out. When the lights go out, you press the trigger button to race. The time taken from when the lights go, to when you press the button is your REACTION TIME How to Win a Formula Ethara Race To win a Formula Ethara Race you need a fast car and you also need fast reaction times. Fast Cars - the better you build your car, the faster it will go. Formula Ethara Cars will race the 20 metre distance somewhere between 1.300 and 1.600 seconds, depending how well they are built. Fast Reaction Times - this is how long it takes for you to press the trigger button after you see the signal to go! The Total Race Time is most important at Formula Ethara Competitions. You need a fast car, but you also need fast reaction times. Race Start and Race Time Data Explained If you look at the far right picture above you will see that: All times are displayed in the measurement unit of seconds Times are shown accurate to three decimal places or one one thousand of a second. A millisecond! REACTION TIME - How long it took to press the trigger button. Lane 1 shown above has a reaction time of 0.383 seconds RACE TIME - How long it took the car to travel from the start line to the finish line. Lane 1 above = 1.538 seconds TOTAL RACE TIME - This is your REACTION TIME + RACE TIME of the car. For Lane 1: 0.383 + 1.538 = 1.921 seconds Formula Ethara Racing Rules All team members must race the car at least once Each team has 6 races The teams final Race Result is the AVERAGE of all of the 6 races Research & Investigate - Test Your Reaction Time! Fast Reaction Times are important in Formula Ethara Racing. Lets now see how good your reaction times are. Get ready to test yourself and also record each of your reaction time results. Click on the Reaction Time tester picture below to get started. Use the Free Practice mode and don't forget to record each of your reaction time results. You will need this data for the next Activity. Click to open the Reaction Time tester. Averages and Decimal Places - Need some help? To learn more about the concepts of Average Number or Decimal Places, click on the video links below: Average Numbers Explained Decimal Places Explain Activity - What's Your Average Reaction Time? Now go to the Ethara Science and Math section of the #EtharaAtHome portfolio and complete the Reaction Time data activities. Input your reaction times into the table Calculate your average reaction time Calculate total race times and average total race time. Calculate your Theoretic Best Total Race Time. Research & Investigate - Average Speed Speed is defined as the rate at which something moves. Speed is related to the Science of motion. We can use Math to calculate the speed of an object. Studying the motion of Formula Ethara car could get very complex if we were to consider factors like acceleration and friction. We are going to keep it simple and calculate the AVERAGE SPEED of a Formula Ethara Car. Watch the next video to learn how to calculate AVERAGE SPEED Video - Calculating Speed, Distance and Time Convert Meters per Second (m/s) to Kilometers per Hour (km/h) In the video, AVERAGE SPEED is being calculated using the units of Meters for Distance and Seconds for Time. AVERAGE SPEED is then stated as Meters per Second (m/s). Its more common for the average person to talk about speed using the units of Kilometers and Hours (km/h). The video does explain conversions, but here is a very simple rule to help you convert speed from (m/s) to (km/h). SPEED IN METERS PER SECOND x 3.6 = SPEED IN KILOMETERS PER HOUR Yas Marina Circuit in Numbers Some of the following Yas Marina Circuit data will help you complete the activities section in the Portfolio: Lap Distance = 5.554 km F1 Race Laps = 55 laps F1 Race Distance = 305.355 km Lap Record Time = 1'40.279 - 1 Minute and 40.279 seconds (Sebastian Vettel, 2009) Average Lap Record Speed = 199 km/h Maximum Speed = 339 km/h Activity - Which is Faster, Usain Bolt or a Formula Ethara Car? If you have watched the calculating speed video, go to the Ethara Science and Math section of the Portfolio and complete the activity sections to: Calculate the average speed of the Formula Ethara Car in meters per second Calculate how long it would take (in theory) for a Formula Ethara Car to do one lap of Yas Marina Circuit! Convert average speed of Formula Ethara Car to speed in Kilometers per Hour Which is Faster? Usain Bolt or a Formula Ethara Car? TO GO DIRECTLY TO UNIT 6 - CLICK HERE GO BACK TO MAIN MENU - CLICK HERE
