79 Can a car decelerate faster than 1G ?
Yes -- F1 cars can pull 4-5G under braking with the help of high
downforce, sticky tyres and efficient brakes. Aerodynamic downforce
can double the effective weight of an F1 car at speed. Sticky tyres
don't slide smoothly but in a series of many small deformations.
These can give very high coefficients of friction (much greater than
1). A less significant factor is the aerodynamic drag caused by the
large wings. The Cd figure of an F1 car can be very high and is even
higher when a car spins.
