Question

why at poles if earth stops rotating then its acceleration at poles remain unchanged?

Answer 1

the acceleration due to gravity at any point

on the earth is given by

g' = g - Rw²cos²A

thus at poles the angle A = 90

thus g' = g

therefore g does not change on the poles

Answer 2

Answer:

No! That’s not true.

To understand the acceleration due to gravity, you first need to know the reason of gravitational force.

The reason for gravitational force is MASS.

Due to large mass, gravity will be high and low masses will have low gravitational force exerted by them.

The acceleration due to gravity is the increase in rate of speed of a freely falling object being pulled by the mass of the Earth, so it doesn’t depend on Earth’s rotation around its axis.
