Everywhere I've read that static friction is usually greater than kinetic friction, but I haven't been able to find the exception to that. So I have two questions: Is there a real life example where the coefficient of static friction is less than the coefficient of kinetic friction between two materials, and how does it work? Secondly, if that were to be true it leads to a semi-paradoxical situation. Imagine the following, there is an incline and a box rests on it. Let's assume the coefficient of kinetic friction is 0.6 and of static friction is 0.4. Let's say the incline is at a degree such that the parallel component of the force to the incline is greater than the maximum static friction but less than the kinetic friction. So if the box was initially moving it would slow down and stop, but once it stops the kinetic friction force becomes static, which is less than the force pulling it down... so what would happen?
