NORTH

A hockey puck launched north from Equatorial Africa would follow the prime meridian on a stationary earth and arrive in London. On a rotating earth the inertial great circle path of the puck takes it to the east of the prime meridian, which the earthbound observer attributes to the rightward Coriolis force. The puck also ends up south of the target due to the centrifugal force.


Legend:
