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.
@@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.

@@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)
@@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.
Wings are not perfectly horizontal and when most lift is needed (take off), the angle of attack is higher. The explanation of the video is incomplete (if not completely wrong) though. I suggest you to watch the videos of Fly with Magnar
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.
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
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.
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
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?
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.
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.
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.
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.
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 ✌
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.
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 ruclips.net/video/w78JT6azrZU/видео.htmlsi=WO4wNK8idlOTQPXa Its Newton’s third law that is correct
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
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?
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.
The hand demonstration is one of the simplest and most effective explanations I've found yet. Cheers!

@@takawolter507 Thank you for the explanation! It's also great that you posted it like 4 times too so that I really understand it!
@@takawolter507finally someone who knows, thanks for writing that so I don’t have to
Like the hand demonstration
It’s not how an airfoil works
@@benderoo6433 So, the explanation is wrong? It is not because of the vertical component of that wind force?

Money....makes an aircraft fly
now all I can think about is a 100$ bill flying an airplane
no. Thats not how it works. You use money to buy the things need for it

@@SquishyUnit69 bro used his own face in a reply
Oooooooooo
This is the best explanation I ever heard ❤
that was a clean presentation brother!
The easy answer is getting me more interested.Perhaps you should do a full video of a long answer.
I never thought of it that way, great example.
Good and easy explanation....1~Luv
Glad it was helpful!
How space crafts fly in empty space, as there is not anything like air?
in thrust, we trust
When I get asked a broad question like that I just say, “It’s sorcery. No one really knows how it flys”
One of the few videos that gives the real answer and not the Bernoulli myth
Appreciate it! :)
Flying is for the brave.
Easy answer ReD Bull gives u WINNGS!
It bugs me that the hand was fingers forward instead of fingers sideways, like a wing

How the steering system works in planes can you explain on it?
How does the high and low pressure define?
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.
So if I put wings on a car it will fly then?
Like the explanation, very simple
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
But it’s still not how it works
What is ACU?
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.
The “pushing up” effect on your hand outside a car window is actually caused by drag, not lift.
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
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?
I like ur way
How does aerobatic planes and fighter jets fly inverted?
Good
There is a difference between gravity and weight… gravity isn’t the “four forces of flight”… weight= mass x weight…
That’s a real pilot’s response
correction: weight=mass x gravity
So how do birds fly and stay in the air without an engine (silly question)
There's nothing belong to gravity when something fly . Only thing is pressure of air
Air weighs 14lbs per cubic foot. Push enough air down, and you go up
Watching this as I’m on vacation in Florida baha
Are you an airplane maker?
ho to come down after going up
How does a really heavy aircraft fly?
Deeewez nuts
What’s going to happen when all the engine turns off😅😅😅😅
thank you this is what i was looking for a real life demonstration with the hand it actually made click now thank you
it’s not how airfoil works
The hand being pushed up demonstrates drag, not lift. This easy version video is misleading and factually flawed.
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.
There NO Lift `force` and NO Drag `force`, it is Aerodynamic force. Lift and Drag are just components in coordinate system.
Im still amaze how tons of baggage can be lift up by a plane simply just doing this principle😊
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.

@@rylanthompson5844 Those are light so the oncoming air can stabilize it enough to keep it airborne.
Thank you for explaining it correctly
Many flights are too pricey

It's sotly prpoes meyr
learn aerodynamics and you will immediately know how a plane flies
How does it work when a plane goes up and down
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

Its Newton’s third law that is correct
what about an helicopter
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

What are private jets?
A plane with a jet engine instead of the usual piston engine or turboprop 😐
A Turbo fan propelled plane that is privately owned.
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?

The propeller blades makes downward fore which creates lift
It's black magic 🎩 and unatchural if man was meant to fly he would have wings. 🤪 lol I wonder how many people actually believe that?
