Angular momentum of a half filled waterbottle....

AI Thread Summary
The discussion centers on the angular momentum of a half-filled water bottle when it starts spinning. Participants emphasize the need for clarity regarding the axis of rotation, noting that the center of the bottle is not a defined axis. The conversation highlights the importance of specifying details in questions to facilitate accurate answers. The relationship between the bottle's angular momentum and its initial state is questioned, prompting further exploration of the factors involved. Overall, understanding the specifics is crucial for addressing the query effectively.

when compared to the angular momentum of the bottle at instant when it started spinning.
 
Spinning around what axis?

about its center.
 
The center is not an axis. The axis is a line. It may go through the center. But there are many lines going through a point.
Look, you need all the details of a question before you can even think about an answer. You cannot expect people to read your mind and figure out by themselves what you want to ask.
 
Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
