Question

If g(acc due to gravity) is not constant, then why is its value taken as 9.8 m/s2

Answer 1

Explanation:

It should be noted that the strength of gravity is not a constant - as you get farther from the centre of the Earth, gravity gets weaker. It is not even a constant at the surface, as it varies from ~9.83 at the poles to ~9.78 at the equator. This is why we use the average value of 9.8, or sometimes 9.81
