The value of acceleration due to gravity at different locations

Galileo stated “In the absence of air resistance, all bodies fall at the same acceleration, which is approximately 9.8 m s^–2”. The value of acceleration due to gravity at different locations are given below:

• At the surface of the earth (average) - 9.8 m s^–2

• At the equator - 9.780 m s^–2

• At the poles - 9.832 m s^–2

• At Chennai - 9.782 m s^–2

• At the centre of the earth - zero m s^–2
