The belt spins as fast as the wheels.
One of those links was pretty good. If you got onto a tredmill with roller blades, and were pulling on a rope that is attched to the wall in front of you, wouldnt you move foward? Eventually, the force foward of the thrust will overcome the backwards force of the belt tot he wheels.
Plane takes off due to the fact that the plane is moving foward, and thats what confuses people. The plane is moving foward due to the fact that the engines are producing thrust, not the wheels.
