Question

Define acceleration due to gravity. Why does the value of acceleration due to gravity vary as you move from

the poles to the equator? ​

Answer 1

The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation and the centrifugal force. In SI units this acceleration is measured in metres per second squared or equivalently in newtons per kilogram.

Answer 2

Answer:

As the earth is an oblate spheroid, its radius near the equator is more than its radius near poles. ... From the above equation, it is clear that acceleration due to gravity is more at equator and less at poles. So if a person moves from the equator to poles his weight decreases as the value of g decreases.

Values of g in SI: 9.806 ms-2

Values of g in CGS: 980 cm s-2
