Plane on a treadmill poll...

[ISAtlanta300]

What you just admitted to is that the wheels spinning means nothing - which is what we want you to see. So, you got your -10 and you +10 - PERFECT!! Plane is going nowhere fast. Now fire up the JET engines to 100% - the plane moves forward yes? And if not - what is stopping it from moving forward.

Yes, but you are not applying 100% of anything to the treadmill. The treadmill in the original question, is asked to match the speed / force / thrust of the plane.


It's simple.. if you can accept that -10 and + 10 = Zero than you'd have to accept that the thusters were set so that the plane is at +10 (10MPH forward) and the threadmill is moving at -10 (10 MPH Backwards), so the plane is stationary, (AT ZERO), wheels spinning and all, UNTIL you fire the engine at 100%. This is logical. Cause if the treadmill is at -10 and the plane's engines are off, then the plane will move backwards on the treadmill at -10 (10mph backwards), just like if you were to just stand still on a moving treadmill. Even with rollerblades. Correct so far?

If you accept the principle that this magical threadmill is able to keep the plane stationary at -10/+10 then you'd have to accept the principle, that if all the stars align, and the treadmill is magical enough to instantaneously match ANY motion, thrust / speed of this plane, that it theoretically be possible to hold the plane stationary AT ANY SPEED, UNTIL the thursters are able to overcome this opposite force/resistance/etc. to start moving forward and lift off (eventually)
