Stop the world, I'm getting dizzy

In summary, the conversation discussed the idea of stopping the Earth's rotation by having everyone in the world walk in the same direction or using parachutes to stop. It was mentioned that angular momentum would be conserved and calculations were made for the angular momentum of the Earth and 6 billion people walking at 1 meter/second. The conversation also drew a comparison to the airplane on a treadmill problem.

Okay if everyone in the world started walking east at the same time would that be enough to stop the world from spinning, at least until they stopped walking? If we all had parachutes to use to stop would we be able to keep the world stopped?

Angular momentum would be conserved …

so what is the angular momentum of the Earth, and what would be the angular momentum of 6 billion people of average mass at say 1 metre/second walking round the equator? :smile:

Wouldn't this be similar to the airplane on a treadmill problem? Save that people really are stuck on the tread mill.
