it is not necessary...tht da coeff.. of friction shud alwayz be less dan one..!! when ever we polish things we reduce da friction provided by dat surface. but wen we superpolish dat surface..we actually increase da friction to such a limit dat..da coeff of friction is greater dan one..!! polishin-- coeff.....less dan one.. super polishin-- coeff..mite be more dan one..!
