But there is more than lack of thrust and poor wing design that gets a paper plane to come back to Earth. As a paper plane moves through the air, the air pushes against the plane, slowing it down.
This force is called drag. To think about drag, imagine you are in a moving car and you put your hand outside of the window. The force of the air pushing your hand back as you move forward is drag. Finally, the weight of the paper plane affects its flight and brings it to a landing. Weight is the force of Earth's gravity acting on the paper plane. Figure 1 below shows how all four of these forces, thrust, lift, drag, and weight, act upon a paper plane.
A paper airplane in flight will experience an initial thrust forward which begins its flight and lift from air which will help push it upward.
These forces are counteracted by drag that acts in the opposite direction as thrust and gravity which will constantly pull the plane towards the ground. Well, what do you think? Would you like to start experimenting with these forces? In this aerodynamics science project, you will make a basic paper plane and then slightly alter its shape to increase how much drag is acting on it. You will investigate how far the basic paper plane flies and compare that to how far it flies when the drag is increased.
How will adding drag affect your plane's flight? You can answer this question with just a flick of your wrist. The following resource can be used to convert inches and feet to metric units i. What was the most important thing you learned? Naucila sam da detaqno planram projektnu nastavu kako bih dobila najbolje reyultate od ucenika. Prakticni deo koji sam od vas preuzela, upotpunio je moj teorijski deo nastave. Science Buddies materials are free for everyone to use, thanks to the support of our sponsors.

Much more. UncleMuzza said: Aerodynamics in a quiet controlled setting, not outside. It's useful to see the theory in action without the need to explain why outside factors like wind etc are affecting our results.
Thanks for your support. MsJen said: How planes fly even though they are really heavy. This gave a really good representation of how planes fly and also how drag works. Because of learning about drag, I also learned more about how the parts of the wings on a plane help it fly.

One factor is the kind of design used to build the plane. In this activity, you will get to build a paper plane and change its basic design to see how this affects its flight. There is a lot of cool science in this activity, such as how forces act on a plane so it can fly, so get ready to start folding! Share your story with Science Buddies! Yes, I Did This Project!
