What is the physics behind paper airplanes?

Paper airplanes are subject to the same physics as any jet you see in the sky. The forces of thrust, lift, drag, and gravity all work together to send your homemade aircraft flying. To understand how these forces work to create flight, think about movement: something has to push that plane forward.

What is the science behind why a paper airplane glides?

When you throw a paper plane in the air, you are giving the plane a push to move forward. 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.

What is the science behind a plane flying?

Airplanes achieve flight by using lift, drag, thrust and weight. They use a specially designed wing to generate high pressure below the craft and low pressure above it. Weight is caused by gravity, and it pulls down on the aircraft; drag is produced by the friction created by the air particles passing the plane.

Why do paper airplanes eventually fall?

When we throw paper airplanes, they do not keep flying continuously. Instead, they fall down to the ground because of the force of gravity. Gravity is an invisible force that pulls objects to the center of our planet Earth. Objects with greater mass (like Earth) pull more than objects with less mass (paper airplanes).

How does the wings of a paper airplane affect its flight?

In addition 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 airplane will glide.

How does drag affect a paper plane?

As a paper plane moves through the air, the air pushes against the plane, slowing it down. This force is called drag.

Why do some paper airplanes fly farther than others?

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.

How does the type of paper affect a paper airplane?

The type of paper used can affect its weight and the amount of friction that exists. How the plane is designed can also vary tremendously. The design of the wings, body, nose and tail can all drastically change the way the plane flies.

What affects how far a paper airplane flies?

The size and shape of its wings, particularly the main wing, affects its performance. A lightweight plane with large wings glides well but travels slowly, while heavier planes with smaller wings travel more quickly and cover larger distances.

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 are the forces acting on a paper airplane?

In general, there are four aerodynamic forces that act on the paper aircraft while it is in flight: Thrust, which keeps the plane moving forward; Aerodynamic lift, acting on horizontal surface areas that lifts the plane upward; Gravity, which counteracts lift and pulls the plane downward; and.

What are the propulsion techniques used in paper airplanes?

Another propulsion technique, creating high launch velocities, involves the use of elastic bands for “catapults”. Walkalong gliding involves the continuous propulsion of paper airplane designs (such as the tumblewing, follow foil [8] and paper airplane surfer [9]) by soaring flight on the edge of a sheet of cardboard.

How do Folding Paper Wings affect the aerodynamics?

After the folding there are still gaps between different layers of folded paper (tearoff edge). These and the kinks transversal to the airflow may have a detrimental effect on aerodynamics, especially on the upper side of the wing. In some models the surfaces are not aligned to the direction of flow acting as airbrakes.
