A slip can occur while you are flying straight or while
turning. By definition, a skid can *only* occur in a turn.


Well, maybe so, but my understanding of a skid is a little
different. In my notion of a skid it is a flight condition in which
the amount of rudder applied is too great for the amount of bank
applied. Thus, in my thinking, if you are flying at zero bank -
not in a banked turn - ANY application of rudder will result in a
skid, not a slip.

Please let me know if I have this mixed up!

The wings are at different airspeeds in a turn regardless of
whether you are slipping, skidding or coordinated. They are
at the same airspeed in straight flight regardless of
whether you are slipping or coordinated. If you are
turning, and the airflow is coming across the fuselage from
the outside of the turn, you're in a skid. If it's coming
from the inside of the turn, you're in a slip.

Straight flight is a coordinated manuever where both
wings are at the same airspeed. Banked, turning flight is
a coordinated manuever where both wings are at
different airspeeds.
