If the rotation of earth increases, the weight of body decreases.

Then why the gravity or weight on Neptune is less?

Priyanshu said:   8 years ago
Mass of earth decreases as velocity increases so gravity also decreses.

Mahesh K said:   8 years ago
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?

Hamza said:   8 years ago
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.

Good explanation @Akshay.

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

Thank you all for explaining this.

Good explanation, Thanks @Akshay.

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.
