The hand demonstration is one of the simplest and most effective explanations I've found yet. Cheers!

[@C0ttageChees]

Came to the comments to say this, too :) With all other explanations I'd watched, I didn't come away with an understanding as exactly what caused the pressure diff.

[@takawolter507]

@@C0ttageChees It's not that simple. I was confused by the video because I would have thought that the hand naturally goes up if you dangle if from a car window because slanting it will make wind hit the bottom and push it up. airplane wings aren't tilted like that. When the airplane wing is slicing through the air, the airplane wing is made so the air has to take a longer route to get to the other side. Because air has to move faster at the top of the wing in order to get to the end of the wing in time to meet the air flowing at the bottom, the air is more apart from each other and the pressure is lower than the bottom. Lower pressure=lighter than bottom air=lift. sorry for the long reply.

It’s not how an airfoil works

[@kornelijekovac9793]

@@benderoo6433 So, the explanation is wrong? It is not because of the vertical component of that wind force?

[@benderoo6433]

@@kornelijekovac9793 Nah, it really has to do with the shape of the wing causing differing pressures at the top and bottom of the airfoil... I am not an expert, I just have a decent understanding. I'm not really the one to consult for an in-depth explanation, but in simple terms the larger surface area of the top of the airfoil distributes the air molecules over a larger area, compared the the bottom of the wing. There's plenty of great videos made by people who actually know what they're talking about... (not me, of course)

[@benderoo6433]

@@kornelijekovac9793 The hand demonstration is right in some regards, but is far from a perfect analogy.

[@lntg]

@@benderoo6433In what way is the hand explanation not a perfect example? There is lower pressure above your hand, and high pressure moves to areas of lower pressure. Voila.

[@Edwardianschool]

The “pushing up” effect on your hand outside a car window is actually caused by drag, not lift.

[@michaelpointer9724]

It's lift by definition. Drag is the force component in flow direction, lift is perpendicular. They are just normal components of the pressure distribution

[@Workerbee-zy5nx]

Flying is for the brave.

[@david_porthouse]

When the wing starts from rest, it dumps a starting vortex. Vorticity of opposite rotation bound up with the wing generates lift by the Magnus effect. When the wing stops, it dumps a stopping vortex. If the wing moves intermittently, it dumps a vortex street. This can be visualised.

[@LEXICON369]

It bugs me that the hand was fingers forward instead of fingers sideways, like a wing

[@rudybhai1657]

pressure is inversely proportional to velocity. while lifting up there was very heigh velocity on upper side of its wings and low velocity on bottom side. PRESSURE IS HEIGHER AT LOWER PART OF ITS WINGS. THEREFORE IT LIFTS UP. IT FOLLOWS BERNOULLI'S EQUATION. I'm not sure but this is what I learnt in my class

[@Benm8_]

But it’s still not how it works

[@Jonymecasso7692]

How does the high and low pressure define?

[@Sammyboy74]

Like the explanation, very simple

[@FastshortvideoEurop]

There's nothing belong to gravity when something fly . Only thing is pressure of air

[@baviation1631]

There is a difference between gravity and weight… gravity isn’t the “four forces of flight”… weight= mass x weight…

[@williammickelson403]

That’s a real pilot’s response

[@filipinoliftstravelseats]

correction: weight=mass x gravity

[@vivekchintala8873]

How the steering system works in planes can you explain on it?

[@andndmmcmnf1321]

So if I put wings on a car it will fly then?

[@Prongsie2]

I know this but with the aircrafts with propellers located front, shouldn't the propellers generate air in a way that it will push the plane backwards?

[@mohamedsamir8906]

How does aerobatic planes and fighter jets fly inverted?

[@BluelarkAviationLLC-qc6rg]

Lift greater than weight? In most circumstances Lift will equal weight except generally when "pulling" G's. Excess thrust is what allows airplane to climb on takeoff. Once in a stabilized climb and no airspeed changes, all of the airplanes forces are equal. I would argue in all the basic senses of flight, forces will equal each other always.

[@hud86]

Air weighs 14lbs per cubic foot. Push enough air down, and you go up

[@karasimon6766]

So how do birds fly and stay in the air without an engine (silly question)

[@marcopalacios7250]

How does a really heavy aircraft fly?

[@ajy1980]

Im still amaze how tons of baggage can be lift up by a plane simply just doing this principle😊

[@JeremiahMelanie]

I like ur way

[@tylisirn]

While Bernoulli contributes (pressure difference), Newton (opposite and equal reaction force) is much more important - the wings predominately create lift by deflecting the airstream downwards which pushes the wing upwards. This is how even a completely flat airfoil like paper airplane can generate lift when it can't generate any pressure difference, and how airplanes can fly upside down even though the pressure difference is on the wrong side of the wings.

[@michaelpascual2731]

You do know that I was joking with the comment that I had made about it being black magic and if man was ment to fly he would have wings it's in fun like the videos he provided I am aware of the fact that we're able to fly and how it works but thank you and stay safe peace ✌

[@sebastiansiswick2903]

Ah you see, the air hitting the wing and being deflected is creating a pressure difference between the sides, as pressure is simply force/area, and there is more air hitting the lower wing meaning more force in the same area so higher pressure than above. However, the only reason an aircraft flys Newton’s second law.

[@vlatkopopovski2685]

It is wrong approach researching the creation of Lift force and Low pressure at upper side of the wing. I explain the aerodynamic cavitation and existence of Lee side aerocavern, and creation of Aerodynamic force.

[@vlatkopopovski2685]

There NO Lift `force` and NO Drag `force`, it is Aerodynamic force. Lift and Drag are just components in coordinate system.

[@BestRobloxPlayer747]

How does it work when a plane goes up and down

[@Benm8_]

Thank you you are asking the right questions because if this theory was correct then a plane shouldn’t be able to fly upside down yet it still does kzbin.info/www/bejne/rWibe4dslt-lkLcsi=WO4wNK8idlOTQPXa Its Newton’s third law that is correct

[@gkrees9509]

why is it that it doesnt work by just adding these wings to a car ?! why are all the prototype flying cars so complicated and designed like a helicopter instead of just adding wings and an thruster to it?

[@Ashpro_566]

Deeewez nuts

[@mikes6961]

If horses ran faster lift would have been discovered way sooner than it did. Of course if an inventor wanted to fly, a stout wind from a storm would have given him an idea. Every kid has stuck his hand put a car window and discovered lift.

[@laxmidevinetam3456]

It's sotly prpoes meyr

[@alexanderzawydiwski9534]

No, no no you guys did it all wrong this this is how those two things sticking out of the plane are called wings and they make lift and then the Spinney thingy creates the thrust

[@carparelli_]

thank you this is what i was looking for a real life demonstration with the hand it actually made click now thank you

[@Benm8_]

it’s not how airfoil works

[@Edwardianschool]

The hand being pushed up demonstrates drag, not lift. This easy version video is misleading and factually flawed.

[@Money.motion10]

AND SPEED

[@crazybird199]

Not quite with the hand, but decent start. A wing actually generates lift via a special shape called an airfoil. This does the same thing but allows the wings to be essentially level and still produce lift. Many airplanes also slant the wings up compared to the fuselage to deflect the oncoming air down and further reduce air pressure on top.

[@rylanthompson5844]

Explain paper airplanes.

[@crazybird199]

@@rylanthompson5844 Those are light so the oncoming air can stabilize it enough to keep it airborne.

Its pretty much the same of a plane (If im wrong correct me please) The airplane has a flat surface on the bottom. A curved one on the top The helicopter has the same shape on its blades. In which it spins and just like a plane It makes lift.

[@Benm8_]

The propeller blades makes downward fore which creates lift
