How do paper airplanes fly?

Answer 1

paper airplanes fly depending on their wing angle (dihedral), weight, and wing design.

small paper planes wings go faster if you put some weight in the front. paper planes

with large wing glide more slowly and float. if its windy outside you may be lucky

enough to throw it and the wind will pick it up.
They have wings that create lift for the airplane to stay in the air.
Newtonian lift and pressure differential above and below the aircraft's wings.

Answer 2

This is as much as I know:

If you have small wings, launch your plane fast, it's a dart. If it has big wings, it's a glider and you need to throw it slower. Stunt planes rock. As you throw an airplane, the force from your hand carries it in the air. But soon, force runs out and gravity takes over. That's why planes always hit the ground, no matter what. Plus, a good plane looks like the letter 'v' from the back. If you have one with one wing tilted to the side, when you throw it, there won't be enough lift on that wing and it will barrel roll to the ground. With 'v' shaped wings, the plane that is straight has more lift than the other one, and corrects itself. If your plane is unstable, add verticle fins to your planes wings by folding them upward. If your plane flys to the right, add a verticle Finn on the left wing. Vice Versa if it's the other way around. If it barrel rolls, check to make sure you have a 'v' formation wing. Here are a couple of designs for paper airplanes:

1. The bulldog dart:

1. fold in half lengthwise to find your center line.

2. fold the top two corners down to the center line.

3. flip over. The top part will now form a triangle. Fold the bottom two corners of the triangle straight into the middle.

4. fold the nose inward, this should make the plane no longer pointy.

5. fold the plane in half lengthwise. be careful

6. fold the wings slightly, so they look like a 'v'.

Now for the Harrier, it's a glider.

1. Do steps 1-2 on the bulldog dart

2. Fold the big triangle down to the bottom of the paper.

3. fold in the second set of corners.

4. after you do #3, there should be a triangular point sticking out. Fold that to cover the two flaps.

5. Fold in half along the spine, with the triangular point sticking out.

6. Almost done. Finally, fold the wings back on themselves to form the wings. Voila.

Answer 3

They have wings that create lift in order for the plane to stay aloft in the air and because its so light the g-force (gravity) does not pull it down fast.

Answer 4

The air causes paper airplanes to fly. Since it has a flat area when it's being thrown, it catches air which keeps it soaring in the air.

Answer 5

The same properties that allow any object with wings to fly. A forward motion through air, air flowing over the wing faster than it is flowing under the wing causing lift.

Answer 6

they float because of the upthrust of water (the natural force of water which causes things to float) is greater than the weight of the paper airplane
