Quiz 65: Weight and rotation
You know, the earth is rotating around its axis.

Well, this makes us lighter due to centrifugal acceleration.

Having said that, the question is: how much would 1Kg weights (in the equator area) if the earth stops rotating?


PS: Consider the earth radius 6371Km.

At the equator, the speed is:

Therefore, the centrifugal acceleration is:

The weight linked to this ac is 0.0337Kg.

Therefore, if the earth stops rotating (don't do it please!) the weight will become 1.0337Kg, because the centrifugal force will disappear.
