... (2) With the known density distribution in the earth, the shape of a fluid, rotating body can be calculated and a value for flattening derived for this body. The result of this calculation is that the measured f and the value calculated for a fluid model are nearly the same, indicating that the eart ...

Lecture Gravity
... Potential is scalar field (actually mathematically easier to deal with) – more sensitive to distant mass distributions (because 1/r2 gets smaller with distance faster than 1/r). Total gravitational field is sum of contributions from all masses. Surface gravity is associated with (1) figure of Earth, ...

Apparent Forces
... We must take into account the accelerations of the coordinate reference frame in addition to those of the fluid itself. Apparent Forces are used to include the effects of an accelerating coordinate reference frame (e.g. rotation of the earth). Two apparent forces: Centrifugal force and Coriolis forc ...

Geodesy

Geodesy (/dʒiːˈɒdɨsi/), — also known as geodetics or geodetics engineering — a branch of applied mathematics and earth sciences, is the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three-dimensional time-varying space. Geodesists also study geodynamical phenomena such as crustal motion, tides, and polar motion. For this they design global and national control networks, using space and terrestrial techniques while relying on datums and coordinate systems.
