2.0 Variation of acceleration due to gravity

2.1 Variation of acceleration due to gravity $(g)$ due to shape of the earth
2.2 Variation of acceleration due to gravity $(g)$ due to altitude
2.3 Variation of acceleration due to gravity $(g)$ due to depth
2.4 Variation of acceleration due to gravity $(g)$ due to rotation of earth

The value of acceleration due to gravity $(g)$ varies from place to place on the surface of any planet (say earth). It also varies as we go above or below the surface of the earth.

The value of $g$ depends on following factors,

1. Shape of the earth

2. Altitude

3. Depth

4. Rotation of the earth
