# Super Car Science Project

Improved Essays
Do you want to know what makes super cars go fast? Tune in to this science project to find out. In this science project, you will see aerodynamics, drag, and wind speed do its process on cars. In my experiment,on each car, there are streamers on them.When my wind tunnel turns on, streamers that fly everywhere will represent drag, and streamers that stick to the car will represent aerodynamics. In real life, they use smoke to figure out where drag is.Sometimes, they will put streamers on the car and use this method to determine drag, aerodynamics, and wind speed. Aerodynamics is what allow cars to go fast. It is the way that air moves around an object. The more streamlined the car is, the more aerodynamic. If the car is flat, that will also …show more content…
One example is like a horse pulling a trailer with a bunch of very heavy stones on top. The trailer is dragging the horse down a lot.. So,the engine has to work two times harder because it is pulling drag. In wind tunnels, if air behind a car is flying everywhere, that is showing drag. Race cars are very stream lined, so drag is not a problem for them, unlike sedans and minivans, which usually have a max speed of 100 mph. If they did have drag, they would probably come in last.So less drag will make a car faster. This data will show where a car needs improvement.
Wind speed is the rate at which air moves in an area. The faster a car goes, the stronger the wind will get. Wind speed helps aerodynamics a lot. A car traveling 150 miles per hour, the wind speed will be very high. That tells there is a lot of air on the car, which means the car has to have aerodynamics for wind speed to work, or else it will slow down real fast. This data will help show where wind speed helps the car go faster.
Aerodynamics makes a car smooth with the wind speed. But if there is drag, that car will slow down. The goal was to find out which one of my 3 toy cars is fastest. If the streamers fly everywhere, that area will represent drag. But if the streamers stick to the car, there is aerodynamics. This science project was a lot of fun and has taught a lot about how cars use aerodynamics, wind speed, and drag to help them go

Careers in the automotive field are always a great necessity in today’s society. You can always count on the fact that people will need assistance with their automobiles. Throughout the years up until today, the evolution with cars have skyrocketed; with style, dynamics, technology, and also safety precautions. A key component that designers still take into consideration is how far along designs have come from the birth of the seemingly prehistoric Hot Rod. The technology available today are a great phenomenons that designers in the early 1930’s could only dream about.…

The purpose of this project is to be able use the speedometer readings to approximate the distance traveled with a midpoint Riemann sum. This method is used to approximate the value of a definite integral using subintervals. To complete this project, I first had to ask my parent to take me for a twenty minutes drive on the street. As a passenger, I first had to record the initial odometer reading and then for every two minutes, I ask the driver for the exact speedometer reading and record my data on the sheet.…

How physics applies to nascar The main impetus behind the foundation of NASCAR was William "Charge" France occasion spot for dashing fans, and France got to be included in hustling autos and advancing races. In the wake of seeing how hustling principles could change from occasion to occasion and how unscrupulous promoters could slip off with prize cash, France felt there was a requirement for a representing body to endorse and advance dashing. He assembled individuals from the hustling group to talk about the thought, and NASCAR was conceived, with its official joining in February 1921. France served as NASCAR's first president and assumed a key part in forming its improvement in the sport's initial decades.…

Questions: Answer all questions given What kind of relationship did you see in your D vs T graphs (both hand and computer)? Do these relationships make sense? Explain! In the distance versus time graph for the hand graph, there is an exponential increase the in the distance traveled; as time progresses, the distance the car travels increases a little more, as the slope is not a straight line, but instead slopes upwards, with slopes later in the line being steeper than the slopes before.…

In order to overcome the friction, the car, or anything for that matter, has to work harder. “Friction converts energy into heat and sound which removes energy from your motion, causing the vehicle to roll to a stop as its energy is removed.” (Mousetrap Cars, 2004) How fast or how far it moves is dependent upon the design of the car…

The purpose of the experiment was to determine how altering the amount of mass in a makeshift rocket will affect its distance. Our hypothesis stated that when more mass is added to the rocket, its distance will also increase. To investigate this theory, we conducted an experiment in which the mass of the rocket would be changed using differentiating amounts of water. To measure the height of the bottle rocket, we took rope and attached it to the girth of the liter bottle to determine how high the rocket launched in the air. We concluded our experiment to brief that the independent variable is the volume of water, and the dependent variable is the rope that was used to measure the rocket's height.…

“The car had already turned in lap times that were far better than the ones of sports cars drivers” And in a very innocent asking from an innocent press, Audi might have had the car racing murdered for as we have known it. Well, cheers guys. The car was an automatic version of the new RS7, and yeah, it’s the one who got this passenger ride the previous year and the track on which they were racing was California’s tricky Sonoma raceway.…

The vehicle is straight and far. Our car went straight because on our v-log our car had a consistent measurement because most of the time our car stayed 11ft. Our car stayed straight because it had a consistent distance, which means that our car went straight and didn’t veer. The vehicle went straight and far. Our car went far because on our v-log it says that our car went 6 ½ ft in 5 ½ seconds, which means our car traveled far in a short amount of time.…

Gauging Education Through Standardized Testing It has long been a debate in any realm on how you measure performance in order to categorize potential of an individual. For instance, the NFL combine measures tangible evidence, but yet it is only an indicator and not a true prediction of a player’s ability. Similarly, public education struggles to accurately predict the potential of student achievement. Although it is extremely rigorous to identify, the process to assess performance in public education has drawn wide skepticism on a national level, both politically and publicly, as substantiated by ProCon.org (2015). There are a variety of reasons we can substantiate statistically why students are failing to achieve the mark on standardized tests.…

The force of my car depended on how much my car weighed and also the amount of force from the lever arm that made it move. I determined the length of my lever arm by just cutting the mousetrap arm at the back axle and had it so it was even with it. I did it there so it would have a force going directly up to get enough acceleration to get the big wheels going in the back. I had too much weight in the back so it did not take off with a lot of acceleration. Instead of taking off quick, it took off slow and when it did, it would not make it the five meters that it was supposed to.…

The mousetrap is the power source. The wheels, which are CD’s will have no traction if not for the balloons being wrapped around them. With the wheels being CD’s they are thin and therefore more aerodynamic and will help the velocity and speed of the car. Then with the pens being hollowed out, it helps with the air and power from the mousetrap to flow through the pen which is attached to the wheels and helps the energy be sent to the wheels and thus, making the car move forward. When designing the car, we chose to use eye hooks because tape and glue would help with the sturdiness and help keep the mousetrap and the wheels connected without breaking.…

Newton’s three laws are important in car safety. When a car crashes, the passengers and the car it self, slow down quickly, which causes harm to the passengers. A car crash comes with an immense force, because of the quick stop. Newer cars have safety features that soak up the kinetic energy in collisions, which are; seat belts, air bags and crumple zones. Kinetic energy is the energy of motion.…
