Your question does not ask a conceptual question about physics, it simply asks users to solve the exercise you call "the Devil's problem". That you ask us to solve the exercise not by saying "Solve this for me" but by asking whether a given number is the answer doesn't change anything in my eyes - how is an answer supposed to make the ...

First, note that not all homework related questions are off topic here. However... I wasn't interested in learning or understanding any physics methods; my interest was to find out whether 13 is indeed the answer for the problem in question. It's the Devil's dozen that made me interested. For me, the value of the posted solutions is that they prove that 13 ...

Let's kick things off with the most important one - the homework close reason, which currently reads Homework-like questions and check-my-work questions are considered off-topic here, particularly when asking about specific computations instead of underlying physics concepts. Homework questions can be on-topic when they are useful to a broader audience. If ...

The SE will block your account from posting new questions if your existing questions are judged to be low quality, but the exact criteria they use have never been disclosed - presumably to stop people from gaming the system. I have read your existing questions, and you are obviously enthusiastic about physics. Can I suggest you ask in the Physics Stack ...

Even though you have eliminated an explicit reference to opinion, this does not change the fact that IMO the question is still opinion-based. I can answer yes/no/I think so/I don’t think so without reference to any physical law or principle, and my answer would be just as good as anybody else’s.

I did imply in my question that I wanted to see a solution, but that was merely because I wanted to verify. I wanted to get convinced whether 13 is the answer. We call these check-my-work questions. Yours is exceptionally interesting, and perhaps the community will vote to reopen it on that merit. But generally check-my-work questions are not high-quality, ...

I agree with the close voters that your question is unclear, and I've elaborated in a comment there. If you believe another user is behaving in a way that violates our community standards, you should use the flagging system to bring the situation to the attention of the diamond moderators, which include me. I have to say that there is no evidence from your ...

Welcome to Physics! In its current form (v4) it’s unclear to me what your post is asking about. One symptom: it does not appear to contain a question that ends in a question mark. Your self-answer suggests that you have solved the problem you were having by locating a factor of two. That’s typical of check-my-work questions, which our community has decided ...

Yes, closing does seem to discourage a lot of askers, especially those who don't understand how Stack Exchange sites work, but it's supposed to encourage them to improve the question, when possible. We close questions that are off-topic, for obvious reasons. We close duplicates because they've already been answered. The point of early closure is not to ...

If you were just looking for someone to confirm that the answer to the problem was 13 without showing any work, I don't see how that would make the question a better fit for the site. To me, that would be off topic as a "check my work" type question, and a particularly bad one because no work was shown. An answer of "yes" would not be ...

I don’t understand your question. BTW there may have been multiple close reasons and the system takes the one with the more votes (I think), and I may have voted to close because it was unclear. From your question: How can this proof be generalized to a multiple-object system, considering the forces between those objects are conservative? Why can’t you ...

Honestly: your question is not very good for the site. Ignoring losses, does that mean a AA battery could theoretically lift 10,620.9 pounds, 1 foot high? YES. But of course, that’s not a very enlightening answer. The next paragraph talks about efficiencies, but it’s not possible to answer “what’s the best efficiency you can hope for” as this would ...

With due respect, I think you're missing the larger point here. This question may or may not be a homework-style question to you, but it is definitely a homework-style question for the site. In other words, what matters is the value of the question to the site rather than to the OP. Don't get me wrong: this is a cute problem. I'm likely to use it as an ...

I think the reason is that it starts to have too many answers which I didn't expect. This isn't quite right. We decide whether to close a question on the merits of the question, not the answers. The problem with a question of the form What are examples of X? is that there are many possible answers, and so it naturally attracts many partial answers, instead ...

Your meta question is actually not a question. It is a comment that you cannot understand why a main site question of yours was closed. As a result: I dunno how your non-question in meta can be answered, Even if we understand your meta post as a kind of question, it is not possible to answer it in any way except by formulating a speculative opinion on the ...

I can actually see several reasons why this question doesn't fit, including the engineering reason that it is closed for. I'll go through my opinion on them. For off topic as engineering, I don't think that blurb you quoted gives the whole picture on why something could be seen as an "engineering" as opposed to physics question. The problem is ...

It seems (to me at least) that most of elements you mention here should be included as part of an edit of your OP: “I’m aware of related questions but: [Question 1] is related to ... However, my question is really about...“ This would specifically differentiate your question from others, and the edit would send your modified version in the queue for ...

Your question was reviewed for reopening, and the reviewers unanimously voted to leave it on hold. Strictly speaking, that's why it wasn't reopened. Now, to give a bit more detail, when I look at your question I basically see this structure: [a homework problem] I'm confused that internal forces changes kinetic energy with respect to center of mass frame ...

I think you're somehow thinking closing questions means they are "undesirable". This is not true of this one: it just needs to be clarified. I did not participate in the VTC but reading it I have to admit that I would have voted to close this question because it lacks clarity. The onus is then on the OP to edit the question and clarify why a ...

Yes, an off-topic question can be reopened, if the author edits it so that it falls within the site guidelines, which are linked in the Closed notice, and in Emilio's first comment above. Your question currently looks like a "check my work" question, which is why David closed it. That close reason doesn't just apply to checking arithmetic, it also applies ...

I think you need to reframe the question somewhat. If this is something you came up with yourself, it would probably be best to remove the whole puzzle aspect and weird framing. It makes it seem like it's something you've found somewhere else and are just looking for the solution to it. I think the big thing that makes this like a homework and exercise ...
