SCIENTIFIC PRINCIPLES (SPEED) Speed relates to my PYP because speed is like areo dynamics and areo dynamics makes stuff go faster so speed is like areo dynamics. Speed makes objects go faster than it's usual pace. And that is why I picked Speed because Speed is a big broad Scientific Principle.

The speed of cars has produced lots of green houses gases. The reason for this is because the exhaust gives of green houses gasses from the engine. So over time we make the planet a better place to live in and a worse place because of the green house gasses.
 * === Causation: Why is it like it is? ===
 * Function: how does it work?

__ CAUASTION __ How has the technology changed the speed of cars? The technology has changed the speed of cars because we have invented better engines better exhaust and better safety in cars. This has happened over the years because over time we learn new stuff so every year the cars just get better and better.

__ CAUASTION __ Why has the speed of cars changed over the years? The first practical car was invented by Karl Benz in 1885. It was a 3 wheel car with a 958cc engine that developed about .8 hp. It had a top speed of around 8 mph. The speed of cars was changed to go faster because it just couldn’t get you around fast enough __ CAUSTION __ When was the speed of light first discovered? The speed of light was first known about in ancient Greek. But the fact that light had speed as well shocked scientist. However it was not until modern times that equipment was sensitive enough to see it.

__ CAUSTION __ Who created the first car and why? The first "car" was created in 1769, when Nicholas Cugnot designed a steam powered road-car. The vehicle was built at the Paris Arsenal, and was used by the French army to move cannons around the place. It was a three wheeled car with the boiler in the front with the engine. While his "car" was able to reach speeds of approximately 4 MPH.

__ FUNCTION __ Why is formula 1 cars streamlined and how does it help? Formula1 cars are aerodynamically designed in order to reduce drag when they are racing. Every component of a formula1 car plays an important role in maintaining handling and increasing speed for the car. Due to the competitive nature of the sport and the importance of every split second each component of the car is tested to see how it increases air friction when on track. It is the air friction that can slow down the car and loose anything from split seconds to a few seconds for a driver throughout a lap. The recent introduction of a new aerodynamics package for Ferrari, has demonstrated the impact that this technology can have on the cars performance. __ FUNCTION __ When was the Lamborghini developed to what it is now? The First Lamborghini was made in 1963 by Ferruccio Lamborghini, The Lamborghini was shaped like it is because that was its original style. But without knowing they made the car very aerodynamic because it is in the shape of a point so less wind blows on it so it can go faster. And after that the Lamborghini court on so they kept making it like that. The Lamborghini is made out of Carbon Fiber, except the roof and I believe the doors, too. __ FUNCTION __ How does the shape of a car effect its Top Speed? Aerodynamics effects how fast it can go. because if you have a car shape like a box it will not go as fast because of it boxy shape but if you have a car shaped like a Lamborghini Gallardo air flow will be easier to go around the car making the go faster but if you do have a car shape like the Gallardo there will be a lot of down force. __ FUNCTION __ Who designed streamline cars and why? Streamline Cars Ltd was the company responsible for making the Burney car designed by Dennis Burney.

Sir Charles Dennistoun Burney rose to fame as an airship designer, best known for his work at Howden on the R100 for Vickers. With the ending of the airship programme he used some of his ideas to create a revolutionary car. Starting in 1927, thirteen cars were made at Maidenhead. Each was different, as they were intended as showcases for his patents rather than for serious production. __ FUNCTION __ What is the top speed a car can go and why? A car powered by a jet engine has travelled faster than the speed of sound. And that is 700 MPH (1120 KPH). That is because of its enormous jet engine.
