**Acceleration Of Gravity**
symbol g*)</STRONG> *

By the International Gravity Formula,
<math>g = 978.0495 [1 + 0.0052892 sin^{2}(p) - 0.0000073 sin^{2}

(2p)] </math> centimeters per second squared
at sea level at latitude p. See
gravity.

* The standard value of gravity, or normal gravity, g, is*
defined as g<math>_{o}</math>=980.665 centimeters per second squared,
or 32.1741 feet per second squared. This value corresponds closely to the
International Gravity Formula value of g at 45° latitude
at sea level. * *
