This video was made when I was less than 1 year old and now I'm using it for a physics assignment.

thanks, now clear to me

I didnt understand the fineman diagram

This wrong. Very wrong. Lift over a wing, airfoil, has NOTHING to do with the Coanda Effect, nor “equal transit.” Nor, as accurately stated here, Bernoulli. As an airfoil moves through air, the perfect vacuum at the surface of the back of it pulls air above it downward. A low pressure zone is created above the top-back of the airfoil that pulls down additional air from above. All of this “scooped up” air is accelerated down the backside, trailing edge, of the airfoil*. Opposite but equal action equals lift. Basically a plane is a horizontal rocket-horizontal ballistic flight**. As for Bernoulli: Bernoulli involves flowing, constricted, and NON-COMPRESSIBLE fluids. Air is highly compressible, is not constricted over an airfoil, and is, relative to the airfoil, stationary, not flowing***. As air pressure differentials are involved, the Bernoulli equations approximate well enough the processes and forces involved, and so are often utilized in explaining lift. *There are videos of planes landing where condensation in the low pressure above their wings is seen. Some even showing that air being shot down the trailing edge of the wings. **Interestingly, looking at the energy consumption of an airplane versus a rocket it is revealed that gravity is the primary source of energy for sustained flight by an airfoil equipped aircraft. Hence unpowered glide-ratios, auto-gyros, gliders, etc. ***It is the airfoil that is “flowing” relative to the air.

tnx

perfect video thanks

This is only and explanation, NOT the proof (mathematics, science or experimental).

Nice job I have learned alot

Thank u for the tutorial I will be looking forward too splitting my own atom

Why did we take area as r²?

Your diagram says "air speed over the surface is lower" means it should have higher pressure compared to area near lower surface. Means, ball should deflect down but your experiment shows the other way.

3:18 why is still udd and no uud

Would it be better use 1/180 so even per radian

Using candle is best unit of light measurement and limit all design below sunlight intensity is adaptable standard for all design i propose

This guy is a scammer, half video and then bye-bye

Perfect example. Thank you.

It sucks a lot. Nice video.

The first part glueing the tube,what if the tube was a foot long,then wrapped in copper wire,then take sheet of magnet,cut the sheet in thin strips glue them on anotHER bigger tube but on the inside run them sn ns sn ns so when speaker vibration Is 500 per second or more,you can make electricity,i wonder how much,? That is my question a few watts to run the speaker,

I'm really starting to warm up to you math guys ❤thx

Thank you sir

you didn't explain y rad is used rather than degree😏

learning this now and a video from 16 years ago is helping me

Thanks

Hello , could you share what function generator are you using, and could it be replace by a signal generator?

Thank you. Very clear explanation.

Thank you.

Hi, if lifting the pile of coins 1m in 1 second uses 1 watt of power. How many watts would it be to do the same lift in .5 secs. And would that still be 1 Joule of energy used?

In my estimation the effects of the front and rear of the ball or tube cancel each other out and the lift is caused by the under side pushing air into an oncoming air stream ( higher air pressure and turbulence) whilst the top surface pushes air with the oncoming air stream ( lower air pressure and turbulence ).

thanks

why does air cling to the surface becasue speed is slower?

I'm sryy for asking really basic/naive question But Please may I know, how did you get the area = R2 (r square)🙏

youtube is actually better than school

Wow amazing

beuluia effect

This is a brilliant explanation, easy to follow. And love the dry sense of humour. 😂

Please learn the difference between a stream and a jet. Coanda Effect applies only to jets and has no relevance to a simple airfoil where static pressure is constant across the entire fluid.

How do I buy one of these?

Folks in the UK have different spelling than we do here in the USA. We spell the work “physics” instead of fizzics - but I understood what they meant.

Your conclusion is correct regarding the direction of emf according to Fleming's left hand rule for motors. Thanks.

Well done, sir.

yes, but what is an atom...this is supposed to be for beginners

Remember the 1950s movie Forbidden Planet where the scientist Morbious projected his daughters image by thought? Looks just like the pyramid devices today !

Thank you so much for the explanation, sir. Educators like you are massively underrated.

Wow the simple video with a simple example blows every other video out there that tried to complicate the explanation. The demonstration succinctly proves the fluid being deflected downwards and thus creating lift due to the opposite and equal reaction.

But the air upard on the cylinder gets curved around it because of coanda effect and its caused by entrainment of air, so the upard air (at atm. Pressure) pushes it downward and it gets curved around the cylinder. So cyclinder is not what applying the force on air to get it curved, its the atmosphere, how the hell we can say it the air is moving down so it apllies an upward force on cylinder, equal and opposite forces occurs when the force on object 1 v mes form object 2, here object 3 (the cylinder) is experiencing force out of nowhere

love your explanation!

Great video, you deserve more recognition!😍
