Friction is directly related to air particles.

When we say that friction is high, it means that you're colliding with lots of air particles, and hence you can't speed up as easily.
Thus, the more air particles you encounter, the higher the friction.

The faster you go, the more particles you will encounter in a given time; hence at higher speeds, the friction is higher.
