no
if the power comes from the wheels or turbines on the wings it does not matter
it could come from 100 people running, it does not matter
it is the direction that counts, not the way it moves
if you drive a car on a conveyerbelt at the same speed it is moving or in a plane or swim against a current with the same opposite speed you will remain in the EXACT same possition
that's exactly the point...the plane doesn't use it's wheels for take off, unlike th car.
For the 3rd Law of Motion to apply, the power should be at the wheels for the forces/velocity to cancel. But here the power is not in the plane's wheels (which are free rolling)

the fucking engines on the side move the plane
the wheels do fuck all they aint needed apart from reducing friction on the ground
THE WHEELS DO FUCK ALL!!! THE ENGINES MOVE THE PLANE
they power wind through the jets and move the damn thing!!
end of ... if you think it wont take off ure a fucking idiot its common sense !!

The plane will take off, there is no debate. The aircraft will not be affected by the ground moving what so ever. If you were worried about thatthen you could take off in the same way you would on grass. 15 degrees of flap and get the thing off the ground as quick as you can, then once you are at the correct speed, rotate and climb.

but ed, the wheels... they must slow the plane down loads.

The ammount of friction would be increased. We could draw a digram showing all the forces acting on the aircraft

them tiny little wheels give enough friction to slow down engines which propel and fly a machine that weighs 155 tonnes

no, the engines in reverse the air brakes and the wheel breaks stop the plane

i was being sarcastic, as that would be the only way the plane wpuldnt take off, if the wheels force of the friction from the wheels was stronger than the force from the engines

but when the plane is connected to the ground via the wheels
ok i had a thought about it on my drive home and have concluded that we are both right under different variables and situatiation

anyway ... the ground is already a moving conveor belt and the plane takes off ...
ok its slow moving but still moving

Depending on where in the world and what direction the ground is moving at about 1000 miles an hour.

Reverse thrust and disk brakes do the slowing down.

I think the main assumption to make is that the conveyor belt is at a fixed speed and not increasing with speed as the plane accelerates.
Plus make the assumption that the runway is long enough for the plane to get up to a sufficient speed in order to take off. Surely it will take longer to accelerate to the necessary speed where the air force is sufficient enough to give lift.
In which instance the plane will, eventually take off.
If the conveyor belt is the same length as the plane and at a fixed speed. No chance. There isnt sufficient enough wind resistance in order to give the necessary lift.
