Its when the frame of reference is rotating ( specifically with a constant angular velocity I believe). I don't think it is when an object is rotating relative to another object. Even still...Is the Corialis force always zero at the equator for some reason that I'm missing? The mathematics of the ficticious force seem to indicate three possible scenarios.
That leaves 4 possibilities for F_cor
...The Earth is not rotating
... The Body is not moving
3) m= 0 ...The body has no mass
... The bodys motion is parallel to the axis of rotation.
None of those seem to be unaminously satisfied specially at the equator... So, since Deep Thought implied it, I must be wrong. I just still cant see it.
