Discussion Overview

The discussion explores the behavior of two objects with opposing or identical angular momentum when placed in water. It considers the effects of angular momentum on their motion and interactions, particularly in terms of drifting closer together or apart, while also addressing the role of friction.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that both objects will eventually stop spinning due to frictional drag from the water.
  • Another participant questions whether the objects will drift closer together or apart, indicating a focus on their relative motion.
  • A further participant introduces the scenario of negligible friction, prompting a clarification of assumptions in the discussion.
  • One participant emphasizes the importance of clearly stating assumptions and specific questions to avoid ambiguity in the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the effects of friction and the assumptions involved, indicating that multiple competing perspectives remain without a consensus.

Contextual Notes

Limitations include assumptions about friction and the need for clarity in the questions posed, which may affect the interpretation of the scenario.

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?
 
Physics news on Phys.org
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.
