Slip Ball Deflection
The slip ball deflection is caused by the non-gravitational forces acting on the aircraft in the lateral/athwartship/y-axis. In air on a conventional fixed wing aircraft this is principally caused by the aerodynamic forces generated on the airframe by lateral incident flow generally termed "sideslip". If the incident flow is coming from the starboard side then the lateral aerodynamic forces act to port and cause the slipball to deflect to the starboard and vice-versa.
The location of the slip ball relative to the aircraft cg does not affect the slip ball steady state response.
