this channel is CRIMINALLY underated, this is the best video i found cmplaining lift

Hey! Good video I like how short and to the point it was. Good explanation regarding Newton's 3rd Law, very easy to understand. Did not touch on the pressure-velocity fields surrounding the airfoil. Air moves faster on the top of airfoil (not due to equal transit time) and creates a pressure gradient that also pushed the airfoil upward. Coanda effect is also only applicable to jet flows and the air in the atmosphere acts as a continuum, so it is not applicable. The air stays attached to the surface because otherwise there would be no matter and acts like a vacuum. Overall good job, but there are multiple theories to lift not just conservation of momentum.

Not gonna lie dude You're quite good at this These are some simple yet rare concepts for pre college students So who are you You should make these videos more often if you can Btw I'm your 10th like on this video

cool

Finally another vid :D

Thanks for watching. Much appreciated!

pls come back

That makes sense...

That is not the Coanda effect, the Coanda effect is the viscous entrainment of fluid by a jet of the same fluid moving through it. What you are describing is call the continuum hypothesis, and it says that a fluid contains no voids, because it they did, there would be a pressure gradient which would force fluid to fill that void. By this logic, a wing could never stall. Also, this is a pseudo ski effect illustration that suggests the molecules of air below the wing bounce off the wing and are forced down. This is also a misconception. Finally, the flow pattern shown with the air flowing downs at the angle of attack would predict that lift is proportional to the sin of the angle (while if molecules bounced off the bottom it would suggest a sin square relationship). Sadly, the coefficient of lift varies linearly with the angle of attack, until stall! Hence, this is falsifiably wrong!

Yes, yes, yes, the airplane is “ lifted” airborne not sucked airborne. Newton’s 2nd and 3rd laws apply.

No you need io explain in simple words
