Re: [Phys-L] conserved momentum thru gas...

How is conservation of momentum 'transferring' through scores of miles of
gas?

Not sure I fully understand the question, but the molecules collide, which does not change the total momentum. Yet, there is another factor to consider. Gravity. This provides the centripetal force acting on the molecules so that there is an interaction to transfer momentum and change their velocity.

Is that what you were thinking?
