    Consequently, the ball must “fall back”, which will result in the ball moving along a curved path relative to the merry-go-round. Thus, from the point of view of an observer sitting on the merry-go-round, the ball would appear to be “pushed” by an imaginary force (called the Coriolis force

    UNDERSTANDING THE CORIOLIS FORCE

    2012-12-4 · A ball thrown between two friends on a merry-go-round will appear to them to take a curved path.
