The weight of bodies my change somewhat from one location to another as a result of the
variation of the gravitational acceleration g with elevation. At 45° latitude, the gravitational
acceleration as a function of elevation 'z' above sea level is given by;
g = a – bz ,where a = 9.8066 and b = 3.32 × 10-6s².
