The brake force is proportional to the square of spool speed. Therefore, when the spool speed is fast, brake force is much larger than when spin speed is slow. You might have noticed that centrifugal reels cast well even with slow casting speed, like pitching, and you feel that lure flies at the end of casting.

Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The more dense components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis.
