Coriolis - "compound centrifugal force"
When transforming Newton's laws to a rotating frame of reference, the Coriolis force appears, along with the centrifugal force.
The Coriolis and centrifugal forces are proportional to the rotation speed. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame. The centrifugal force acts outwards in the radial direction and is proportional to the distance of the body from the axis of the rotating frame.
These three additional forces are termed either inertial forces, fictitious forces or pseudo forces. These names are used in a technical sense, to mean simply that these forces vanish in an inertial frame of reference, and that they cannot be traced to an originating source body, like an electric charge or a nucleon.
