OK, I have seen this question posted on a couple other message boards I go to, but seeing asd most of the people at those messageboards don’t have a large knowledge of physics, I am posting here in hopes to get the correct answer.
Imagine a plane is sitting on a massive conveyor belt, as wide and as long as a runway, and intends to take off. The conveyer belt is designed to exactly match the speed of the wheels at any given time, moving in the opposite direction of rotation.
Can the plane take off?
I say no, because the plane will not move relative the the ground and air, and thus, very little airflow will occur over the wings (the engines will create a small amlunt, but not enough.) However, other peopel are convinced that since the wheels of a plane are free spinning, and not powered by the engines, and the engines provide thrust against the air, that somehow that makes a difference and air will flow over the wing.
So what’s the real answer here>
