it won't move
since resulatant force/velocity is 0

But machan nothing to do with resultant velocity of plane ...

A-Air Plane
W-Wind
E-Earth
(horizontally) ->
v(A,E)=v(A,W)+v(W,E)

and if the plane is stationary on the ground because of the effect of conveyor belt going the other way,
v(A,E)=0
if the plane is moving v(A,E) is not 0
(i think most of the people took earth and wind as the same thing, its not)
so v(A,W) cant be zero other than in the case of v(A,E) = v(W,E)...IF that does not happen
v(A,W) is not 0 so
there is wind blowing relative to the plane's wings...there for it'll lift off(Bernoulii's theorem)

affa..ehema takeoff karanna patta hulagak tiyenne onee

..(plain eke speed eka wage)
mata hitune wind speed=0 kiyala..
any way thanxx..

hey but u didn't tell anything abt wind in ur question
if u did this as practically in a vacuome u absolutely couldn't be take off ur plane.

oya kiyana de bernoulii theorem ekata anuwa hari wennath ba. mokada plane eka take off speed eken yanne belt ekata sapekshawa misak wind ekatawath earth ekatawath sapekshawa newai.
oya plane eka take off karanna nam api plane eke wings haraha wind eka plan eke take off speed eken yawanna one
oya dapu videos wala plane ekatai belt ekatai ekama speed eka thiyeenawa kiyala proof karannath ba

kanishka87 · Sep 4, 2009

it wont takeoff since the plane is not moving forwards there by no air pressure difference between the top part of the wing and the bottom hence no lift therefore no it cant takeoff
