Legend

ac

 = centripetal acceleration

v

 = velocity

r

 = radius
Fc = centripetal force

m

 = mass
FN = normal force
Ff = force of friction
Fg = force of gravity

¤½¦¡
Centripetal Acceleration
ac = v2/r
Centripetal Force
Fc = mac = mv2/r
For level curves with no skidding
g = v2/r
For banked curves
tan = v2/gr
