How it can happen please give detail information

Why Earth rotates from West to East in southern hemisphere and East to West in northern hemisphere?? Is this true,if yes then explain please.

Hi grinkle I just want to figure out that only Earth hasn't acceleration due to gravity, any massive bodies have, just like sun has 272 m/s^2 acc^n due to gravity. So, I only want to know that why should we take g as constant for higher massive body(large dia).

Yaa I agree but when we analyze astronomical model which varies a lot with time and rotation both.So, we should use such constant as a variable.

Acceleration due to gravity is used as a constant throughout the massive body,but it varies due to height and depth & also varies from equator to pole,so it affect the rotational speed of planet from equator to pole.So, why would it takes as a constant.
