Gravity Anomalies - deviations from expected value
If there were no topography (i.e. on the reference elllipsoid) gravity is
given by the reference (or theoretical) value for that latitude

A net force on an object m leads to its acceleration:
When the force is gravity, the acceleration is written as g:
