# What creates drag on a paper airplane?

Contents

When you throw a paper plane in the air, you are giving the plane a push to move forward. … While the plane is flying forward, air moving over and under the wings is providing an upward lift force on the plane. At the same time, air pushing back against the plane is slowing it down, creating a drag force.

## How do paper airplanes reduce drag?

Engineers reduce friction drag by making the airplane more streamlined, the wings narrower, or by using new materials that make the surface more smooth, decreasing the ability for the force of drag to effect it. As the roughness and surface area of the airplane decreases the friction drag will decrease.

## How do you increase drag on a plane?

To increase drag, the plane can have many flaps it can lift vertically, which will help it increase the drag on the airplane, which is useful to help the plane decelerate or roll. To decrease drag, the plane needs to be streamlined, in a tear drop shape, but not so much so as to create too much friction drag.

## What forces act on a paper airplane?

Four forces act on a paper airplane:

• Thrust – the force that propels their airplane (your arm);
• Drag – the friction between the plane and the air, slowing the plane down;
• Lift – the force that causes the plane to go up;
• Gravity – the force that causes the plane to go down.

## What makes a paper airplane fly better?

Thrust is the forward movement of the plane. The initial thrust comes from the muscles of the “pilot” as the paper airplane is launched. … Lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down. It is this difference in pressure that enables the plane to fly.

## Does Drag help a paper airplane go further?

The aerodynamics of a paper airplane will determine the distance and ease at which it flies. The aerodynamics of the plane will need to have little drag and be light enough to defy gravity. … When these four forces are used in balance, paper airplanes will fly longer.

## Why does a heavier paper airplane fly farther?

In adition the larger the paper airplane the larger its wings can be. The larger the wings the greater the ability to generate lift. The longer lift is generated the further the paper airplaine will glide.

## What increases drag?

Drag increases with the density of the fluid (ρ). More density means more mass, which means more inertia, which means more resistance to getting out of the way. The two quantities are directly proportional. Drag increases with area (A).

## How do airplanes reduce drag?

6 Design Improvements That Reduce Aircraft Drag

1. 1) Flush-Mounted Rivets. Even microscopic changes to the smooth surface of a wing or aircraft fuselage can dramatically increase drag. …
2. 2) Gap Seals. The gaps between flight control surfaces and a wing are perfect spots for drag creation. …
3. 3) Fairings. …
4. 4) Wheel Pants. …
5. 5) Winglets. …
6. 6) Feathering Propellers.

## What creates drag?

Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. … We can think of drag as aerodynamic friction, and one of the sources of drag is the skin friction between the molecules of the air and the solid surface of the aircraft.

## Does the size of a paper airplane affect the distance?

“Yes, wingspan will affect flight, however there will be a point where the size of the wingspan will create too much weight and drag to be effective. For a glider, which a paper airplane is the more lift the glider has the longer it can fly.

## What design of paper airplane flies the farthest?

There are four forces that act on a plane when it’s flying. Drag, lift, weight and thrust – this need to be in balance for the plane to fly (Scholastic 2014). From the results of testing design number 2 flew the furthest with both the plane launcher and people throwing it.

## What are the four forces?

Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

## Does paper airplane design affect flight?

When you throw a paper plane in the air, you are giving the plane a push to move forward. … The weight of the paper plane also affects its flight, as gravity pulls it down toward Earth. All of these forces (thrust, lift, drag and gravity) affect how well a given paper plane’s voyage goes.

## What is the longest time a paper airplane has flown?

The longest time flying a paper aircraft is 29.2 sec and was achieved by Takuo Toda (Japan), in Fukuyama City, Hiroshima, Japan, on 19 December 2010.
