AT REST
A hockey puck is released from rest in Chicago.
The puck is seen by the inertial observer to be moving east
with a speed equal to the local earth speed (in Chicago) and
follows a great circle in the inertial frame. The earthbound
observer sees the puck head south, and attributes this to
the centrifugal force. At later times, the puck heads
slightly west due to a higher order Coriois effect.
Legend:
Blue: Inertial Great Circle
Red: Path on rotating earth
Gray: Path on stationary earth
