Q: Can F1 cars drive upside-down?
A: Yes! A Formula 1 car with driver weighs 600kg, but at 100mph the cars can produce around 1000kg of downforce. So when driving on the track, a total of 1600kg pushes the tyres onto the road. Because the aerodynamic force is greater than the weight, when driving upside-down at 100mph 600kg act downwards (weight), but 1000kg act upwards ("aero-force"), pusing the tyres onto the ceiling. However, no-one has tried it!
