What is GROUND EFFECT? 

Welcome.

@Alan Now they dont but in the past they did and next year will too

oposite

Yes, as Avrumi said the opposite. Ground effect, in for example the famous Lotus application, was to push the car down. Failed badly, if I recall correctly.

​@@vatandas1542 ground effect has been used in every F1 car since then, it's responsible for at least half of the total downforce.

Many thanks!

Thank you!

I'm alright with music, but quieter would be better. The high pitch instrument, the banjo, was distracting.

Glad you liked it!

@@flightclubonline cheers :D

Thank you for taking the time to leave us such a positive comment.

Glad it was helpful!

Thank you!

Should, but doesn't

In case anyone coming across this comment is still curious about the question about the tilted lift vector, you can perhaps look into wingtip vortices, which I believe produces "induced drag" (which was mentioned in the video.); and adverse yaw, which is related to/produced by the change in lift vector. You might find thorough answers by searching in those directions. The answer I deduced from my brief research is that the lift vector does stay at 90-degree, as it is really the change in relative wind's direction that caused an inclination in lift force. First, wingtip vortices produce air that moves downward ("downwash"), tilting the lift vector backwards. Wingtip vortices will always be present when flying because it's a byproduct of the pressure difference caused by the airfoil shape, without which planes cannot fly; Second, during rolling actions, one wing indeed moves up (therefore it interacts with wind from above) and one down (thus interacts with air from below), in addition to the wind from straight ahead. As a result, the wings' relative wind actually points slightly upwards for the rising wing and slightly downwards for the falling wing, and along with that tilts the direction of lift backwards and forwards respectively. Disclaimer: I'm neither a pilot nor a physicist, merely someone who's taken a liking to learning about (but with no guarantee of truly understanding) the ins and outs of flying. So take it with a grain of salt and do your own research/ask your instructor!

Thank you very much.

@@flightclubonline thank you but which one of the RU-vid creators?

@@brujo_millonariothe song is: Fresh_Fallen_Snow

@@flightclubonline thank you!

Thank you for the feedback.

Glad it was helpful!

You're welcome

No worries!

Thank you too

@@flightclubonline Go ahead 👍👍

Using Apple's Keynote.

@@flightclubonline how much time do u have to spend on average video? It seems it takes much time

It would crash into the building it's aimed at apparently.

Because the adverse pressure gradiant at the trailing edge of the wing is strengthened in ground effect.

That's good feedback for us. Thank you!

The downwash of any wing is just the inertia of the air molecules. As you know, air has pressure, which means the molecules push each other apart at all times, lift being created by the wing pulling air towards itself is bs and blatantly false. It's also incompatible to the way lift is calculated

An infinitely long wing would only have ground effect in a negligible part of its width 🤪

I love the music and her accent is sweet.

Music I agree...but what's your problem with the accent? I think you might be another insular American without a passport.

Chill. Yes the music could have been a bit less loud. But if being presented with otherwise good content - for free - one can voice the opinion in a more friendly manner.
