Why do paper airplanes fly?

Answer 1

My guess is that when you put forward momentum throwing the plane, there is less wind resistance in the forward point of the plane (if the wings are balanced). The air pressure underneath and above the wings are equal, but gravity starts acting on the plane, so the plane doesn't fly perpetually. Of course, if you give the wings a little rounded top, the Bernoulli's kicks in, giving the wings a little less pressure above than below.

Answer 2

for the same reason real airplanes fly, there is more air pressure on the bottom of the wing than on the top... hence the plane floats.

Aerodynamics What makes a paper airplane fly? Air — the stuff it truly is all round you. carry your hand in the front of your body which includes your palm dealing with sideways so as that your thumb is on proper and your pinkie is dealing with the floor. Swing your hand again and forth. Do you sense the air? Now turn your palm so that is parallel to the floor and swing it again and forth again, like you're cutting it by skill of the air. that is user-friendly to sense the air, yet your hand is able to go by skill of it better easily than at the same time as your hand grow to be grew to grow to be up at a proper perspective. How actual an airplane strikes by skill of the air, or its aerodynamics, is the first interest in making an airplane fly for a lengthy distance. Drag & Gravity Planes that push quite a number of air, like your hand did at the same time as it grow to be dealing with the part, are reported to have quite a number of "drag," or resistance, to transferring by skill of the air. in case you opt on your airplane to fly as far as available, you opt on a airplane with as little drag as available. A 2d rigidity that planes decide on to conquer is "gravity." you opt on to save your airplane's weight to a minimum to assist strive against antagonistic to gravity's pull to the floor. Thrust & boost "Thrust" and "boost" are 2 different forces that help your airplane make a lengthy flight. Thrust is the ahead move of the airplane. The initial thrust comes from the muscle tissues of the "pilot" because the paper airplane is released. After this, paper airplanes are extremely gliders, replacing altitude to ahead action. boost comes at the same time as the air less than the airplane wing is pushing up harder than the air above that is pushing down. that is this massive difference in rigidity that permits the airplane to fly. rigidity should be decreased on a wing's floor via making the ventilation over it better instantly. The wings of a airplane are curved so as that the air strikes better instantly severe of the wing, ensuing in an upward push, or boost, on the wing. The 4 Forces in stability lengthy flights come at the same time as those 4 forces — drag, gravity, thrust, and boost — are balanced. some planes (like darts) are meant to be thrown with quite a number of rigidity. because darts don't have quite a number of drag and boost, they count number on better thrust to conquer gravity. lengthy distance fliers are often outfitted with this same layout. Planes that are outfitted to spend a lengthy time period contained in the air usually have quite a number of boost yet little thrust. those planes fly a sluggish and easy flight.

Answer 4

Their wing allows the to glide not fly.

Answer 5

because scrunched up paper doesnt

Answer 6

because u folded it properly, if it doesn't fly, then u folded it wrong

Answer 7

because its a plane

Answer 8

gravity is light on them

Answer 9

be-cause they are aerodynamic
