Hey everybody, first ever post here on the forums. Read a few of the threads so far and have been very entertained so far. My question stems from a debate I had with a friend while taxiing out to the runway and got quite heated. So much though, that I think we may have irritated the entire cabin within earshot of us. It is a take-off of the old 'Upside Down F1' topic. Here is the scenario: An unlimited resources investor actually puts this to the test and develops a track with miles of flat, straight real estate to work with. A track is constructed that allows the F1 car to get up to speed, create the necessary downforce and then provide a corkscrew gradual enough to maintain enough forward and angular momentum to complete the upside down test. The track levels off perfectly inverted and the F1 car remains planted upside down on the track at speed. Now, IF the investor runs out of money and the track abruptly stops... Initially, does the F1 car fall to the ground due to gravity and wind resistance -OR- flip upwards towards the sky do to forward momentum and residual 'net downforce'? My position was that the 'net downforce' would flip the car skyward - at least initially - and I would LOVE to rub some math in his face the next time this topic comes up.
