Our hypothesis was the rapier plane in print paper would fly the farthest distance, because it had a bigger wing span and light weight paper. Also, we think that the dart plane in construction paper would fly the shortest distance because it has a small wing span and weighs more. We learned that aerodynamics is the study of forces and the resulting motion of objects through air. During this experiment we learned something new, four forces affect a paper airplane. They are, thrust, the forward motion or speed of the paper airplane, for our paper airplanes this is provided by your throwing the plane forward.

For a general description of why airplanes fly and why they crash, I recommend reading the aerodynamics sections of either of my books The World Record Paper Airplane Book or The Kids Paper Airplane Book. I wanted to include a section like this in my books, but due to space constraints, could not. This also allows me to get more technical in some areas.
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.
Lift “How can a heavy metal lift off the ground”? You may ask. The answer to this question is the lift of the wing, and there are two explanations about how the lift are generated. As everyone can see, the shape of the airplane wings is in a stream line form, which is flat along the bottom and curved on the top. The purpose of this design is not for pleasing to the eye, but for the perspective of physics.
It has been determined that winglets create less drag for airplanes, allowing the planes to use less fuel. But, surprisingly, winglets are not used on all airplanes. The reason is that
Here more wing angle and surface creates more down force which in turn reduces speed. But here the rear wing is splitted into two set of aerofoil which is connected to each other. The upper aerofoil is one large single element whereas the lower one is responsible for creating down force. The lower wing when tilted to a certain angle which creates a low pressure region to create more down force below the car. The position of two wings should be relative to each other as if they were very close then the resultant force will be in opposite direction and thus cancel each other.
Body I. The Triangular shaped hat fold A. According to Shari Lewis's basic rules of origami, as stated in her 1963 book with Lillian Oppenheimer, Folding Paper Toys, one must: 1. Choose a flat, hard surface as your place of work 2. Be sure to make your folds straight 3.
The jumper falls with increasing speed until the parachute is opened. The greater air resistance acting on the surface of the parachute will bring the jumper to a terminal velocity and will enable the parachutist to safely reach the ground. Hypothesis I believe the smaller the amount of surface area the parachute canopy has, the faster it hits the ground. With a larger parachute there is more air resistance because there is more amount of surface area. Materials • Plastic grocery bag • Garbage bag • Larger paper clips • Thread • Scissors • Stopwatch • Meter ruler • Plastic cup Method 1) Size of plastic grocery bag was measured.
You will want to maintain a constant, tight body position by keeping your feet and knees together chin on your chest. You do this to avoid the risers from burning your neck as your parachute opens. Once you feel the opening shock of your parachute, you will immediately look up and inspect your canopy to make sure it’s fully opened, and not damaged in any way. You will then gain canopy control by reaching up high, and grasping both the front and rear set of risers. Once you have canopy control, you want to keep a sharp lookout for other jumpers, during
Southwest Airlines tries to save money by simplifying its operating process. Utilizing strategies such as having “One type of aircraft”, “cash-register receipts as tickets”, “no computer reservation system” and “no meal service” are some examples of its low cost strategies. C. Speed and Efficiency Southwest knows that airplanes generate revenue only when they are in the air. Accompanied with the “point-to-point” strategy, Southwest chooses to operate by the most efficient way of adopting the concept of “high average velocity” instead of conventional “hub-and- spoke” system. D. High Service Quality Furthermore, Southwest understands that its “low fares” strategy cannot be achieved at the sacrifice of good service.
