Race cars have dependent wheels. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
Think about this: a plane is driven by engines on the wings, which generate thrust. The wheels on the plane are like the wheels on a hotwheels car; all that attaches them to the body of the vehicle is an axle/suspension system. The spin completely independent of the plane. When a plane takes off on a runway, it is NOT the wheels of the plane that make it go so fast, it is the thrust generated by the engine. Thus, putting a plane on a conveyer belt the wheels will spin backwards at the same velocity (read as speed and direction) as the conveyor belt. That's right, they will be spinning backwards. Since these wheels are independent of the rest of the plane, the thrust of the engines will propel the plane forward regardless of the speed or direction of plane.
