Coriolis Force (for e-w motion)
Suppose now that the object is set in motion in the eastward direction by an impulsive force. Because the object is now rotating faster than the earth, the centrifugal force on the object will be increased.
The excess of the centrifugal force over that for an object at rest becomes the Coriolis force for this zonal motion on a rotation coordinate:
The meridional and vertical components of these forces are:
much smaller than gravitational force
