Coriolis Force Acting On Toy Ball

What at first may appear to be an inane activity performed by physics students is a good demonstration of the Coriolis force at work. Notice how the ball will curve in a bow shape as it passes over the center of the rotating board.


Coriolis Force Acting On A Ping Pong Ball (Overhead View)

A better example is provided by fixing the camera in an overhead view of a table, which is allowed to rotate.

From this vantage point the rotation of the table is indiscernable, and the ball appears to be under the influence of a force moving it in one direction. this is similar to our perception of the Coriolis force on earth.
