Acceleration of Gravity vs. Latitude and Elevation
Acceleration of gravity due to latitude and elevation above sea level.
Acceleration of gravity at sea level and elevation related to northsouth position on earth (degrees latitude):
Acceleration of Gravity vs. Latitude and Elevation (m/s^{2})
Acceleration of Gravity vs. Latitude (ft/s^{2})
Example  Time for Falling Object to Hit the Ground on the Pole or on the Equator
The distance traveled after some time by a free falling object can be expressed as:
s = 1/2 a_{g} t^{2}
where
s = distance (m, ft)
a_{g} = acceleration of gravity (m/s^{2}, ft/s^{2})
t = time (s)
The acceleration of gravity is stronger at the poles than at equator and the equation above can be modified to
t = (2 s / a_{g})^{1/2}
The time for an object at level 1 m to hit the ground on the pole can be calculated as:
t = (2 (1 m) / (9.832 m/s^{2}))^{1/2}
= 0.4510 s
The time for an object at level 1 m to hit the ground on the equator can be calculated as:
t = (2 (1 m) / (9.78 m/s^{2}))^{1/2}
= 0.4522 s
Example  The Weight of a Large Man in Canada vs. Venezuela
The acceleration of gravity in Canada at latitude 60 degrees is approximately 9.818 m/s^{2} and the acceleration of gravity in Venezuela at latitude 5 degrees is approximately 9.782 m/s^{2}.
The weight  or gravity force  of a large man with mass 100 kg in Canada can be calculated as
F_{g} = (100 kg) (9.818 m/s^{2})
= 982 N
The weight the man in Venezuela can be calculated as
F_{g} = (100 kg) (9.782 m/s^{2})
= 978 N
