# What forces affect a paper airplane?

Contents

At the same time, air pushing back against the plane is slowing it down, creating a drag force. 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 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 paper airplanes stay in the air longer?

The aerodynamics of the plane will need to have little drag and be light enough to defy gravity. Paper airplanes also use the forces of lift and thrust. When these four forces are used in balance, paper airplanes will fly longer.

## How does gravity affect a paper airplane?

Gravity helps create lift for paper airplanes. Gravity is the force that pulls objects toward the Earth. … When paper airplanes are thrown up, gravity pulls them down. This movement causes a difference of air pressure on the airplane wings, which then causes lift.

## How does an aircraft fly what are the forces acting on it?

An airplane in flight is acted on by four forces: lift, the upward acting force; gravity, the downward acting force; thrust, the forward acting force; and drag, the backward acting force (also called wind resistance). Lift opposes gravity and thrust opposes drag .

## 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 the weight of a paper airplane affect its ability to fly?

The forces that allow a paper plane to fly are the same ones that apply to real airplanes. … 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.

## Does a heavier paper airplane fly farther?

Changing Mass

In the same way a rock that is thrown pushes its way through the air as compared to a cotton ball, a paper airplane with more mass flies faster and farther than a paper plane with less mass, up to a point. If the mass is too great, the wings can’t hold the plane in the air.

## What makes a good paper airplane design?

We have Thrust — that’s what makes a plane go forward, Drag — that’s what slows a plane down, Gravity — which pulls the plane back to the earth, and Lift — which keeps the plane aloft. To create a successful paper airplane design, you should maximize Thrust and Lift, and minimize Drag.

## What paper airplane flies the farthest?

In 2012, Collins set the world record for the farthest flight by a paper aircraft. Thrown by football player Joe Ayoob, the glider, named “Suzanne,” after Collins’ wife, flew 226 feet, 10 inches (69.14 meters) before gracefully making its way into history.

## Can planes fly without gravity?

Aboard a specially modified Boeing 727-200, G-FORCE ONE®, weightlessness is achieved by doing aerobatic maneuvers known as parabolas. Specially trained pilots perform these aerobatic maneuvers which are not simulated in any way. ZERO-G passengers experience true weightlessness.

## 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.

## How lift is created in aircraft?

Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air. … Lift acts through the center of pressure of the object and is directed perpendicular to the flow direction.

## What happens when the four forces of flight are unbalanced?

If the forces of thrust and drag are balanced, an aircraft doesn’t move. … It is only when thrust overcomes drag that a plane moves forward. When drag is greater than thrust, the plane is pushed backward.

## Which of the forces of flight is the most important?

Air in Motion: Aerodynamics and the 4 Forces of Flight

• Lift. Perhaps the most importance force to a pilot is lift. …
• Weight. Weight opposes the force of lift in flight, directing down toward the center of the Earth. …
• Drag. Drag is the aerodynamic force that opposes the motion of the airplane through the air. …
• Thrust.

## What is Bernoulli’s principle of flight?

In fluid dynamics, Bernoulli’s principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential energy. … When the air speeds up, the pressure also decreases. Past the constriction, the airflow slows and the pressure increases.
