Variation of g (acceleration due to gravity) - cal
... To find the acceleration due to gravity at sea level you can plug in values of G and the mass (in kilograms) and radius (in meters) of the Earth to obtain the calculated value of g: g = GM/r2 This agrees approximately with the measured value of g. The difference may be attributed to several factors: ...
