If the rotation of earth increases, the weight of body decreases.
Then why the gravity or weight on Neptune is less?

Mass of earth decreases as velocity increases so gravity also decreses.

In W = Mass * Acceleration.
How does weight of the body would decreases, when rotation increases. The gravitational force also increases. As W & g. Directly proportional. So, please tell me how does weight of the body decreases?

If spinning speed of earth decreased than weight of the body at poles does not change why?

Basically, it can be said that.
If the speed of rotation of earth increases so will the centrifugal force, which will try to nullify gravity.

Fcentripetal=mv2/r,
m~1/v,
Velocity increase mass decrease.
m~1/v,
Velocity increase mass decrease.

As we all know energy(E)=1/2MV^2 and weight=Mg
So from the first equation we can get M=2E/V^2. Then put this value in second equation, so now the result comes weight(W)=2E/gV^2. So,if V increases then W decreases.
