Title: Paper Airplane Challenge. Problem: The question for the paper airplane challenge is if the material of the airplane is changed to a lighter material than the plane flies further. Hypothesis: If the paper is changed to a lighter material than the plane will fly further. Experimental Design: Use the following three types of paper, cardstock, printer paper and wrapping paper. Make a classic style airplane, and see which flies further. The independent variable is paper,dependent is distance and the constant variables is the size and control plane. Materials: Standard paper, cardstock, wrapping paper, a place to throw (15 ft at least) and at least 2 hands to make the planes. Knowledge on how to make a classic style airplane.

The plane went straight at first then the plane would hit the ceiling and a smackdown would occur. The plane did repeat the smackdown a couple times. The plane glided smoothly and did what a plane is suppose to do. This plane gave best results. The 2ft resulted in this data a drastic and bad crash into the wall. (No lives lost) Conclusion: The lighter plane flew further based on this design. The results did support the hypothesis made, which that the lighter one went further than others. When looking at the table and seeing the averages of the data, the average for the wrapping paper is greater than cardstock and regular paper. When looking at the table some more, the distances, or how many feet the wrapping paper plane flew was significantly greater than the other planes. To closure the hypothesis was correct, but the data might have been affected because the group was not the greatest throwers to start out with and everybody threw a

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.
My hypothesis for the penny cleaning with the chemicals experiment was accepted. The hypothesis was; “If a penny is placed in salt and vinegar, then it will get cleaner than the other chemicals being used”. The data used from the experiment that supports the hypothesis was that the salt and vinegar chemical cleaned a penny the best it had a 90 out of 100.

Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.
Wilbur Wright once said, “The desire to fly is an idea handed down to us by our ancestors who... looked enviously on the birds soaring freely through space... on the infinite highway of the air.” He changed American culture forever when he made the first flight alongside his brother Orville. This invention would have an even greater impact on our culture than cars. Although cars are used every day in America, planes have had the largest impact on American culture. Without planes, our lives would be drastically different, but not in a good way. Airplanes had a major impact on military, commerce, and travel.
The most important factor in determining the lift generated by an airplane is the angle of attack. The angle of attack is the degree measure from the horizontal that a wing is elevated or declined. When the angle of attack is between 1 and 20 degrees, the most lift is generated. To find the lift generated by a particular area of wing in a standard airfoil shape, a teardrop with the fat end facing forward, the equation L=Cl 1/2 (pV2)S. Cl is the lift coeficent, which is determined by the shape of the airfoil and the angle of attack. P stands for the air mass density, V for the velocity of the air passing over the wing, and S for the area of the wing when viewed from above or below.
More cost-effective modes of space transportation are necessary to make further exploration possible. One new, cost effective design is the aerospace plane. These spacecraft are totally reusable and can take off and land like a normal plane (Booth 80). Anything reusable cuts costs. Many commercial spaceflight companies are interested in this design because so much money can be saved.

== = == Hypothesis for the experiment: After I conduct this experiment, I expect and suppose I can recognize and physical changes, identifying the difference these two kinds of changes. Also, I will be able to know some physical and chemical properties of copper (II) sulfate, water, iron, sodium carbonate, hydrochloric acid and magnesium and identify if it is a chemical change or physical change in each part of the experiment.
Normally a plane sits on a runway, spins up its engines and moves forward, gets enough wind under it's wings, and takeoff. In this experiment the plane will not be on a runway, but a conveyor belt and that's matching the speed of the plane going forward in reverse.
The Terminal Velocity of a Paper Helicopter Introduction. Terminal velocity is the resulting occurance when acceleration and resistance forces are equal. As an example, a freefalling parachutist before the parachute opens reaches terminal velocity at about 120mph, but when the parachute is opened, terminal velocity is reached at 15mph, which is a safe speed to hit the ground at. This experiment will be no different, as I will be examining the terminal velocity of a freefalling paper helicopter.
Airplane decent and landing accidents have been statistically proven to be one of the most common forms of airplane incidents. Ultimately accounting for about 37% airplane accidents, there are several different stages of the decent and landing process and several mechanical issues as well as a lack of focus on the part of the pilot can contribute to a faulty landing, ultimately resulting in a minor or fatal crash (Tullo, 2001).
The invention of the airplane, ever since it was invented in 1903 has impacted the world in many ways. It has increased the job rate, boosted the economy, created cultural diversion, and created less pollution than most means of travel. Orville Wright once said, “The airplane stays up because it doesn't have time to fall.” The airplane never did fall and excelled in everything it did, not falling once. The airplane, one of the most important inventions created in the 20th century, impacted travel ways across the world.
On top of this, one day when Mr. Wright returned home from a short church business trip (Mr. Wright was a Bishop), he had brought back toy helicopters, made from a Frenchman named Alphonse Pénaud, that were constructed from cork, bamboo, thin paper, and twisted rubber bands, of which the boys wildly admired (Kelly 8). Later on when the boys were older they both dropped out of high school, Orville because he wanted to start up his own printing business, and Wilbur—though dreaming of going to Yale—because of an injury to his face (Szalanski 1).... ... middle of paper ... ...
