A need for speed will drive you up the wall

A group of four MPhys physics students from the Department of Physics and Astronomy have worked out that a racing car travelling at over 150 miles per hour would be able to stick to the walls of a completely circular speedway track with 90 degree banks - but don't be tempted to give it a try next time you are stuck in traffic.

At speeds of 150mph, the force of gravity acting on a racing car would be less than the frictional force holding the car on the wall, meaning the car would easily be able to stay on the vertical banking.

The students published their findings in a final year paper for the Journal of Physics Special Topics, a peer-reviewed student journal run by the Department.
