Coefficient of static and kinetic frictions ${\mu }_{\mathrm{s}}$ and ${\mu }_{\mathrm{k}}$ are related by 

${\mu }_{\mathrm{s}}>{\mu }_{\mathrm{k}}$

The coefficient of static friction is larger because you have apply greater force to movie because the body initially is in rest- intuitively its harder to start moving an object which is in rest rather than an object already in motion.
