A comparison was made between the geodesic coordinates and the transformed model along the X, Y and Z coordinates and differential coordinates [increment of x], [increment of y], [DELTA]z were obtained.
If now an extra non gravitational force acts on the gyroscope and as a result the gyroscope moves into a world line that is different from a geodesic, then we can not simply introduce local geodesic coordinates at every point on of this world line which makes the equation of motion for the spin d[S.sup.n]/dt [not equal] 0.
