please explain the concept of force of friction limiting and force of friction kinetic.How are they related?

When we try to push an object on rough surface it won't immediately move. As we keep increasing the applied force so as to overcome the friction, at a certain point we succeed, the applied force at the onset of motion is called limiting friction, i.e. minimum necessary for a particular combination of surfaces. But then we can't just stop appling the force, we have to keep applying a force which is lightly less than limiting, and is called kinetic friction force. It's the friction force which must be overcome in order to sustain the motion.
