# What is allowing your paper airplane to overcome gravity?

Contents

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. Bernoulli’s Principle explains how a difference of air pressure is caused due to air moving faster on top of the wings than on bottom.

## How does an airplane overcome gravity?

Planes do not actually defy gravity, though. Instead, the tilt and area of a plane’s wings manipulate the air particles around the plane, creating a strong enough lift that the force of gravity is overcome by the force of the air beneath the wings.

## Why do some paper airplanes fly better?

Pressure can be reduced on a wing’s surface by making the air move over it more quickly. The wings of a plane are curved so that the air moves more quickly over the top of the wing, resulting in an upward push, or lift, on the wing.

## 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.

## When flying a paper airplane what is causing the thrust?

The initial thrust comes from the muscles of the “pilot” as the paper airplane is launched. After this, paper airplanes are really gliders, converting altitude to forward motion. Lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down.

## What makes a plane go up?

What makes a plane go up? Air. A plane flies through the air by continually pushing and pulling the surrounding air downward. In response to the force of moving the air down, the air pushes the airplane upward.

## How do airplanes stay in the air without falling?

For a plane to stay in the air, the lift force needs to overcome the force of gravity. Additionally, the thrust must overcome the drag force, which resists the plane’s motion through the air.

## Do heavier paper airplanes 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.

## 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 is the longest paper airplane flight?

The farthest flight by a paper aircraft is 69.14 meters (226 feet 10 inches), achieved by Joe Ayoob and aircraft designer John M. Collins (both USA), at McClellan Air Force Base, in North Highlands, California, USA on 26 February 2012.

## What are the four forces of flight?

It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.

## How can the four forces of flight be altered?

We can also alter the four forces offlight in other ways• Lift – increasing the angle of attack (when the airplane lifts off orclimbs•Weight – lightweight materials help to keep the overall mass ofthe plane down, so that it can fly with smaller lift force• Thrust – jet engines can vary the amount of thrust, which …

## 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.

## Is a paper airplane in free fall?

If you crumble the paper into a “paper wad”, however, its motion is approximately free fall. … it falls for a relatively short time. … After you have jumped out of an airplane and fallen for several seconds, you are not in free fall, since air resistance is now a factor in your motion.)

## What gives a paper airplane lift?

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.
