The value of g (acceleration due to gravity) varies from place to place and depends on several factors, including:
1. Altitude – Higher altitudes result in a decrease in g .
2. Depth – The value of g changes as we go deeper into the Earth.
3. Shape of the Earth – Due to the Earth’s oblate shape, g is slightly higher at the poles and lower at the equator.
4. Rotation of the Earth – The Earth’s rotation reduces g slightly, especially near the equator.
