Origin of friction

    What is the origin of friction on the atomic (sub-atomic) scale?

    I am just asking what causes friction?

    Do you mean:

    "Why is the frictional force opposite in direction to the direction of travel?"

    Here's the Tomlinson's model on the orgin of friction:

    Please note that this is a very specific example. Your question is actually rather vague, because not only are there different proposed mechanisms for static and kinetic friction, but there are also different models for solid-liquid friction, liquid-liquid friction, etc. It is why Nugatory suggested that you do a bit of homework on your own first and figure out exactly how to ask your question in a more informed manner.
