Your hand is able to move more easily through the air at certain angles. 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. Paper airplanes also use the forces of lift and thrust.

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 force makes a paper airplane fly?
All of these forces (thrust, lift, drag and gravity) affect how well a given paper plane’s flight will go.
Do paper airplanes use Bernoulli’s principle?
In this activity, students can learn one of the principles involved in flight with a strip of paper and their breath. Bernoulli’s Principle states: as the speed of air increases, the pressure decreases. This principle is partially responsible for the ability of an airplane to lift off the ground.
What are 3 facts about paper airplanes?
- LONGEST TIME. The longest time flying a paper aircraft is currently 29.2 sec and was achieved by Takuo Toda (Japan), in Fukuyama City, Hiroshima, Japan, on 19 December 2010.
- LONGEST DISTANCE.
- HIGHEST ALTITUDE THROW.
- LARGEST PAPER AIRPLANE.
- MOST CONSECUTIVE HITS.
- PAPER PLANE THROWN IN SPACE.
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.
What is the best angle to throw a paper airplane?
For paper airplanes, a 5 degree or 6 degree angle of attack is best. The weight of the whole plane divided by the surface area of the main wing is called the wing loading. A heavy plane with small wings will have a large wing load. Planes with high wing loads glide faster so that their rate of descent is high.
How does thrust affect a paper airplane?
Thrust & Lift 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 is the best design for a paper airplane for distance?
If you are looking for the furthest flying paper airplane that can really go the distance, we recommend The Bird. This design is relatively easy to fold, and if it is adjusted carefully it can glide for a very long distance. To optimize your throw for distance, try tossing this paper airplane at a 45° upward angle.
How is motion used in a paper plane?
When you throw a paper plane in the air, you are giving the plane a push to move forward. That push is a type of force called thrust. While the plane is flying forward, air moving over and under the wings is providing an upward lift force on the plane.
How does gravity work on paper airplanes?
Gravity is the force that pulls objects toward the Earth. Lift is the force that pushes an aircraft into the air. 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 gravity affect an airplane?
The earth’s gravitational pull. keeps a plane grounded until the plane is acted upon by the opposing force, lift. Lift – The upward force acting on a plane. Lift allows the plane to rise into the air and maintain flight without falling to the ground.
How does Bernoulli’s principle explain how airplanes fly?
Air moving over the curved upper surface of the wing will travel faster and thus produce less pressure than the slower air moving across the flatter underside of the wing. This difference in pressure creates lift which is a force of flight that is caused by the imbalance of high and low pressures.
What is Bernoulli’s principle for kids?
A high pressure will push fluid towards a lower pressure. If a fluid changes speed, it will be matched by a change in pressure. In one sentence: Bernoulli’s principle says that as the speed of a fluid increases, pressure decreases.
Why can’t we lift without gravity?
The Earth pulls everything down towards its centre, this pull is called the force of gravity. Humans are not physically designed to fly. We cannot create enough lift to overcome the force of gravity (or our weight).
What is the science behind paper?
To make paper, one must break-down the plant cellulose into separate fibers and mix with water. The water dissolves out some of the glucose molecules from within the cellulose. When the pulp is spread out to dry, the glucose molecules re-bond with the cellulose and help hold the fibers together to create paper.
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. However, you must keep the weight and drag in check to avoid flight failure.”
How long can paper airplane fly?
The longest that a paper airplane has ever stayed up in the air was 29.2 seconds. Try a few tests with your own paper airplane and record the time.
Would a paper airplane work with no atmosphere?
A: Without air, the plane wouldn’t be able to fly. The is no air in space, and air is essential for paper airplanes to get the lift they need to fly.
Where should the center of gravity be on a paper airplane?
Center of Mass Adjustments The center of mass of an airplane is the point at which it would balance if suspended from a string at that point. This should be around the middle of the airplane. If the center of mass is too far forwards, the nose will tend to dive down.
What is the best weight for a paper airplane?
According to the makers of HowToMakePaperAirplane.com, the ideal paper weight for constructing airplanes is between 18 and 28 pounds.
What is the most important part of a paper airplane?
Is thick or thin paper better for paper airplanes?
Generally, you want heavier paper for paper airplanes. Too heavy and it becomes too stiff to fold.
How do paper airplanes reduce drag?
One of the keys to reducing drag on the paper plane is to have thin wings. This has to do with a paper plane’s Reynolds Number, which indicates the significance of the viscosity of the fluid (air) on flight.
Does the weight of a paper airplane affect how far it flies?
Increasing the mass of the paper airplane will DECREASE the distance that the airplane will travel.
