Good explanation. Thank you all.

With rotational speed centrifugal force on us outward increases, decreasing the force on us due to gravity.
Repi said:   9 years ago
It's true I think it follows the newtons third law.
Nishan said:   9 years ago
The centripetal force also acts there towards the center. Why does the weight not increased?
Venkatesh said:   9 years ago
@Akshay.

How can you add or subtract the centrifugal force from gravity? Please check the dimensions of both.

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?
Aaaaa said:   8 years ago
Awesome. I would like to know where the weight of body remains same on earth.
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.
