Is rudder required for coordinated turns?

A rudder on an airplane helps make coordinated turns as do turning
brakes on a farm tractor.

That said, most aircraft require a pilot input of rudder to coordinate a
roll input. Little, if any, rudder is required once the roll stops and a
constant bank is maintained.

Without rudder input, the yaw required to change the heading of the aircraft
(as its flight path progresses around the turn) must come from the aircraft
being in a slip.

In an aircraft at high speed and/or with high directional stability, the yaw
rate required is low and the slip angle required is small, almost
unoticeable. The ball will be almost centered

In an aircraft at low speed and/or with low directional stability, the yaw
rate required is high and the slip angle required is therefore large. The
ball will be way off to the side.

Thus glider pilots learn to use their feet rather more than fast jet pilots.
