Which paper falls to the ground first? What seems to keep the flat sheet from falling quickly? We live with air everywhere. Our planet planet is surrounded by a layer of air called the atmosphere. The atmosphere stretches hundreds of miles over a surface of the world.

Take two sheets of the same-sized paper. Crumple one of the papers into a ball. Hold the crumpled paper and the flat paper high above your head. Drop them both at the same time. The force of gravity pulls them both downward.


Have you ever flown a paper aeroplane? Sometimes it twists and loops through the air and then comes to red, smooth Origami Heart Envelope as a feather. Additional times a paper aeroplane climbs upright, flips over, and dives headfirst into the ground. What maintains a paper aeroplane in the air? How will you make a paper aeroplane require a00 long flight) How can you ensure it is loop or change! Does flying a document aeroplane on a blowy, gusty, squally, bracing, turbulent day help it to stay aloft? What can you learn about real aeroplanes by making and flying paper aeroplanes? Let's experiment to learn some of the answers.

The Paper Aeroplane Book
Why is paper aeroplanes soar and plummet, loop and float? Why do they travel in any way? This book will show Musique Le Bateau De Papier you how to make them and explains why they are doing things they do. Making paper eeroplanes is fun and. by using the author's stepby- step instructions and doing the simple experiments he implies, you will also discover what makes a real aeroplane fly. As you make and fly paper planes various Designs, you will learn about lift, thrust, move and gravity; you will see how wing size and ships and fuselage weight and balance affect the lift of a airplane: how ailerons, alleviators and the rudder work to make a plane great or climb. loop or glide, roll or spin. Once you have appreciated these principles of Avion En Papier Simple A Realiser airline flight, you will be ready to take off with types of your own.
Clear diagrams and delightful drawings show each step for making the aeroplanes and illustrate the experiments suggested by the author.





Attempt moving the paper gradually through the air. Does the air push up the slowmoving paper as much as before? Exactly what do you think happens when a paper aeroplane stops moving forward through the air? You can show that a similar thing will happen if you run with a kite in the air. The air pushes against the tilted underside of the moving kite and lifts up. What happens to the lift pressing up on Avion En Papier Qui Vole Bien Et Longtemps Facile the kite if you walk slowly rather than run?

You want a paper aeroplane to do more than just fall slowly through the air. You want it to move forwards. You make a document aeroplane move forward by throwing it. Usually the harder you throw a paper aeroplane the a greater distance it will fly. The particular forward movement of your be airborne is called thrust Thrust helps to give an aeroplane lift. Here's how. Hold one end of a sheet of papers and move it quickly through the environment. The toned sheet hits against the air in its way. The air pushes up the free part of the

moving paper. The paper aeroplane must move through the air so that it can stay upwards for longer flights.


Here is how you can see and feel what happens when air pushes. Location a sheet of paper flat against the hands of your upturned hand. Turn your hand over and push down quickly. You can have the air pressing against the papers. The paper stays in place against your hands. You can see the paper's edges pushed again by the air. Today hold a piece of crumpled paper in your palm. Again turn your hand over and push down. Small surface of the paper hits less air. You feel Bateau En Papier Qui Flotte Sur L'eau less of a push against your odds. Unless you push down very quickly, the paper will tumble to the ground before your odds reaches the ground.

Air is a real substance even though you can't see it. The flat sheet of document falling downwards pushes against the air in the path. The air shoves back from the paper and slows its fall. A crumpled piece of paper has a smaller surface pushing against the air. The air doesn't push back as strongly just like the smooth piece, and the golf ball of paper falls faster. The spread-out wings of a paper aeroplane keep it from falling quickly down to

the floor. We say the wings give a plane lift.


The secret lies in the shape of the side. The front edge of an aeroplane's wing is more rounded and heavier than the rear advantage.




The particular front edges of the wings of any real be airborne are usually tilted somewhat upwards. Just like a kite, the air pushes against the tilted underside of the wings, giving the airplane lift. The greater the angle of the point the greater wing surface the air pushes against. This particular results in a greater amount of lift. But if the angle of the tilt is simply too great, the air pushes from the Le Bateau De Papier Jean Humenry bigger wing surface presented and slows down the forwards movement of the airplane. This is called drag.


Move works to slow a airplane down, as thrust works to ensure it is move ahead. At the same time, lift works to make a plane go up, as gravity tries to make it fall down. These four forces are always working on paper aeroplanes just like they work on real aeroplanes. There is still another way most real aeroplanes and some paper aeroplanes use their wings to increase lift. The top-side as well as the base side of the side can help to give the plane lift.
