When looking at rolling objects, the force of rolling resistance is determined by a coefficient of rolling friction. Is this coefficient constant for an object when both stationary and moving? Or is there a separate static and kinetic coefficient as there is with sliding friction?(adsbygoogle = window.adsbygoogle || []).push({});

I am asking this because the research I have done into this so far, I have only found talk of just the one coefficient. However an object on wheels much surely require a larger force for initial acceleration from stationary than to maintain velocity once in motion? If you could recommend any literature on this subject that would be very kind, I have searched through a number of books on Statics but can't seem to find much information.
