Resistance in wires is like friction as water flows through a river- the longer the river, the more the friction.
A short wire has a higher resistance than a longer one for the simple reason that electrons have to go through a longer piece of wire. Else, we would try to make wire as long as possible everywhere. We see that it is the opposite indeed.
The length but also the diameter of a wire is important.
The material of it is also a relevant parameter.
Actually, we observe that it is mainly the electron on the surface that moves and that's why wires are often an assembly of many small wires.
Finally, I suggest that you post this kind of question on the physics forum.
