A plane is standing on a runway that can move (like a giant conveyor
belt). This conveyor has a control system that tracks the plane's
speed and tunes the speed of the conveyor to be exactly the same (but
in the opposite direction).

Will the plane be able to take off?

No, the plane being stationary wouldn't create any lift

Interesting question. It wouldn't take off, because there is no airflow over the wings. The wings need air moving over them at a high enough speed to create lift, or nothing would happen. Would look pretty funny though. You just buy a dime sack of weed or what?

well if you think about it. if its kind of what they do on aircraft carriers with the catapults. except with a moving runway. if the said runway was moving fast enough it could generate enough speed to allow the plane to become airborne.

you sure Mary Jane didnt visit you tonight?

No. Although the moving conveyor belt would create a bit of drag, thus moving a bit of the air around in the vicinity, it would not be nearly enough to create the lift required to allow the airplane to take off.

Its like running forwards on the backwards conveyer belts in the Airport terminals. You go no-where - fast.

Same will apply to the plane - plus the whole air flow over the wings thing.

PHYSICS FTW!

Lets just say, anybody here familiar with my and some of the posts I've made featuring pix of mi casa knows I don't buy dime bags of swag.

Junk Drawer is a place of whimsy. The thought crossed my mind TO POST this absurdity and I was curious what people would have to say about it.

ps, I have been a unapologetic pot smoker for longer than most of you posting have been alive. I don't advocate it to anyone, but I make no excuses for enjoying it.

so true cause you need to have another force (wind) going against it, to create lift

or that except it also needs air under the wings cause what else is holding it

But if they did have a ginourmous fan the size of New York and the tread mill thing it might work for a little while until it actually gets in the air and has no runway or wind thing

If you melt dry ice can you swim without getting wet??

No for the reasons above about no airflow and lift.

But did you know that if the headwind is faster than the plane is flying then it would fly backwards?

Thats a very pretty pic ATG

Negatory, think about what you're saying.

Aircraft carries launch jets at full power and going the same direction thus speeding them up reallyyyyyyy fast
Dry ice is not water it is co2 (carbondioxcide) solidified you melt it it's gone, thin air sorta speak, good question though, here's mine "water freezes in to ice at 32 degrees Fahrenheit(0 Celsius) at what temp. does ice melt back in to water"? nice pic ATG, although I no longer partake I still love the smell of some good old Crescent county skunk

Yes! Yes it would! You're all wrong!!! The treadmill would have no effect on the plane because it is being pushed / pulled by a jet / propeller! It's not a car! The wheels are not what makes it go, thus the plane would go right off the end of the treadmill with little to no difference. (Until the wings hit the handlebars on the treadmill that is.) As normal, the air would be flowing under the wings, because the plane would be moving forward. If the plane were powered by it's wheels it would only be able to fly short distances and would be more of a jumping car than an airplane. My answer is a solid Yes, the plane would still take off!
