AI Thread Summary
When two balls with opposing angular momentum spin in water, they will eventually stop due to frictional drag from the water. The discussion raises the question of whether they will drift closer together or apart under these conditions. If both balls spin in the same direction, the interaction dynamics may differ. The importance of clearly stating assumptions in such scenarios is emphasized to avoid confusion. Overall, the conversation highlights the complexities of fluid dynamics and the need for specificity in scientific inquiries.

If two balls were close to each other in a pool of water and each had some angular momentum but one was spinning one way and the other was spinning the other way what would happen? same question for if they both were spinning the same way?

Eventually, both objects would stop spinning, due to the frictional drag created by the flow of the water. Either way.
 
I think the OP is asking if they will drift closer together or apart.
 
what about assuming negligible friction? and yes I am.
 
Well, if you are making assumptions, list them in your post. If you want to ask a question, be specific about what you want to know. No one wants to play guessing games to try to read what's on someone's mind.

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
