Have you ever seen a conveyor belt?
Sure have, ifthe wheels aren't being driven, what force is making the belt spin?
quote:
If the plane was attached to the conveyor belt and the belt was going fast enough for the wings to create lift, would the plane lift? Yes.
Nothing to do with the question.
quote:
The movement of the plane is essential, if the scenario described below and the energy created from the engines is not pushing the plane forward, but being used by the wheels to match the conveyor. For the energy to be applied to forward momentum of the plane it would have to exceed the energy of the treadmill, which in this absurd scenario will not happen.
There would be no energy from the treadmill, as the plane is not driven by its wheels. Y'all would have an argument if this was a car.
