FLIGHT DISTANCE IN PAPER AIRPLANES BY: ESTEFANIA SOLIS BIOLOGY 121 SECTION MZ DR. DENISE LEONARD 02-09-2011 INTRODUCTION For the paper airplane lab, we were to fold two paper airplanes and determine what makes for a better plane. We decided that distance traveled would be our dependent variable. As a group, we came to a consensus that what makes a good paper airplane is the distance it travels; the one that flies the furthest is the better of the two. It was theorized that weight played an important role in the overall distance flown by the planes; the heavier the plane, the further it would fly. We decided to use two pieces of paper to make a single airplane; this was our way to make it heavier, as weight was our independent variable.
AC McKinney Speech 377 M-TR 11:30-1:10 Speech #1 Date 6/7/12 How to Skydive Introduction 1) Skydivers have a favorite expression that says, “If riding in an airplane is flying, then sitting in a car is jogging.”(Buchanan) 2) Skydiving is an interesting activity that not only tests the limits of man but provides excitement that’s in some conditions unrivaled 3) First, why should the normal person even consider jumping out of a perfectly working plane? Second, what precautions one should take before planning their jump. Lastly, the preparations one should make leading up to their jump. 4) I chose this topic because I have recently completed two tandem jumps and currently have begun working towards receiving my Skydiving A license.
Problem statement: Does the size of a paper airplane, while keeping the design and paper type the same, affect the distance the airplane will fly? Relevance of the testable question: Once the trials are completed it will be easy to determine whether or not the question of flight distance will be relevant and since according to Hewitt, et al (2007) “in order for an experiment to be considered scientific it must be able to be proven wrong.” (p. 4), it seems likely that the size of the paper airplane will make a difference in flight distance. Literature review: From the information gathered from the following two experiment ideas from both Melanson (2006) and Maranowski (2011) as with any scientific experimental lab, it is the actual lab itself that lends support to the results that make the experiment valid or not. Experimental design: a. In order to complete the experiment the following must be done in the order described below to achieve the desired result: Find an appropriate location where there will be no interference to the outcome of the trial such as a football field on a clear and non-windy day if held outdoors or no air conditioning if the trial will be held indoors, e.g.
This principle is the same that is used to keep helicopters in the air. Engineers have devised a “monocopter” with a single wing similar to the maple seed and have been successful in keeping it aloft in the air with the use of remote control as well as a motor. The Wright brothers used the principle of air resistance in the maple seed fall to design
The advertisement goes after the common sense of the reader because it is very simplistic. Instead of using data, facts, or any statistics it uses simplicity. The add makes the statement that flying from point A to point B is easier with Southwest Airlines than on one their
Identify the controlled variables. A.) Make two airplanes. One small with long wings and one long with short wings. Have two people fly it and see which plane goes the furthest, making sure to match the same amount of force used to throw the planes.
On the back part of my kite, I used the plastic from a garbage bag, hoping it will fly with that. For support, I used wooden sticks that went across from vertex to vertex. I decided these materials would work best because they seemed the lightest. I thought the wind would hit the plastic in a way that it pushed the kite up. The paper and plastic seemed like a perfect, weightless combination to use.
Abstract 3 The physics of roller coasters is very simple. Although it may appear to be very intricate and complicates, even the most amateur physicists are able to grasp it. The entire concept of the physics behind roller coasters is merely in the understanding of potential and kinetic energy. Along with understanding the two parts themselves, it is also quite necessary that you understand the relationship between them. In the article "How Roller Coasters Work" Tom Harris says that the main purpose of the initial ascent of a Roller Coaster is to save up a ton of potential energy.
In this manner he could determine quantitatively aerodynamic phenomena; using an wind tunel with smoke and an aerodynamic balance of his conception he quantified aerodynamic principles using a special photo camera (designed by himself). Due to these experiments he could establish the appropriate profile of wings which were later used for airplanes design. * in 1911 at Reims, H. Coanda presented a two-engine airplane with only one propeller; * between 1911-1914 he held the position of technical director of Bristol Airplanes in England, where he designed several 'classical' airplanes (with propellers) known as
This is a huge advantage because as long as the wind blows there is power to turn the blades of the rotor. However, there are some disadvantages to wind generators. Though this is rare, the blades on a wind turbine can kill birds that fly into them. Some people say that wind turbines are unsightly and that they take away from the beauty of the natural land. However, saying this does not prove a good reason not to use wind energy to generate electricity.
