Abstract
Abstract We examine the induced spin velocity in case of the Earth. Spin velocity is induced
from the conversion of a constrained spatial rotation into a spatial displacement. Its effects on Earth as a celestial body are consequences of its properties, and they are examined in detail.
The induced spin velocity has influence on the semiannual variation of the length of day.
The annual and semiannual variations of the length of day are considered separately. The
measured value in case of the semiannual variation of the length of the day is 5.44% more
than the predicted, while the measured value in case of the annual variation of the length of
the day is 5.36% less than the predicted.
