I have a question about my Physics Stack Exchange post: Kepler's Third Law

Why did my question become off-topic? I just wanted to get a formula and said that I will solve it myself. Why aren't formula questions allowed? As far as i know, the formulas are in conceptual physics. Then, I'm asking a conceptual question. Please, do it at least because you don't admit a conceptual question too. What do you really admit?

EDIT: Giving formulas does not mean ''Solving for you'' If they don't know how to apply that equation or not have any idea about the question, they won't be able to solve question. It depends on what they know. But you all don't have any respect, everyone starts hitting that close button when they see that cool ''homework-exercises'' tag. Answer formula wants at least. We got your homework policies and it seems good. But this is really being funny. The site admits conceptual question and this was really conceptual. That's why everyone does not understand this site.

Please, decide what kind of questions you want. If you want a question like this ''What is that?, What is this?'' Everyone can google it so it doesn't matter. What is this site for then? Examined other stackexchange communities, they are very helpful for a student. If you were right, then why do they answer all kind of questions? everyone gets everything well.

Let's talk about physics.se now. Yes, homework-questions should not be allowed and you are too right. But if you don't admit the formula questions, then that's being too funny. Assume I posted my question here, and asked a formula to solve it myself. Did you solve it for me? No. Who did solve it? Me. What did you show? the true equation him ought to use. Did you give the final answer? No. Does him have any idea about question? If answer is no, then he won't be able to solve it =)

Let's talk about other stackexchange communities, They get both questions. Conceptual-Homework. I posted my questions which I really did not get and took great answers. By the way, I leant everything and saw my faults. They are respectful for students because they see that him does not have any idea about the question. You might be right at homework-questions but really not right at formula questions. Believe in me, by doing this, you are helping no one. If you were really right at this, other stackexchange communties may have been following your policies.

I lost my family from a traffic accident and do not have money to go courses and my physics teacher is too agressive as well. By the way, Trying to post my questions here and that's being off-topic without any reason. I asked them a formula, not final answer or something. Trying to learn something from these communities. Please, be respectful. I hope you change I lost my family from a traffic accident and do not have money to go courses and my physics teacher is too agressive as well. By the way, Trying to post my questions here and that's being off-topic without any reason. I asked them a formula, not final answer or something. Trying to learn something from these communities. Please, be respectful. I'm not telling you to answer homework-questions. If you admit the conceptual questions, then you should answer the formula wants. Like i said, him ought to just ask an equation for question. If he wants the final answer or did not show his idea, then it should be off-topic. It seems like this will be off-topic cause telling true things. I hope you all change your unnecessilary policies. As the last thing I'll say, do not help him with calcuation cause the formula will be enough.

Let me give an example;

Acceleration of center of disc

You did well for this question.

Kepler's Third Law

But look at this question and see what's different between.

(1) The first one wanted you to calcuate and give final answer for him.

(2) The second one wanted you to show a formula not give final answer for him and had said that he will solve it hisself. What's wrong then?

Take my mind as an idea, discuss about this.

  • $\begingroup$ There are plenty of free learning resources for physics that provide formulae. Even if you can't afford anything, as long as you can manage to get Internet access, the information can be found. We don't really want people coming here every time they don't know a formula; that information exists in many other places. $\endgroup$ – JMac Oct 13 '17 at 20:40
  • $\begingroup$ @JMac It is not okay to kick everyone to other forums. What is this site for? It is too easy to google it and it does not take your time to show a thing or help someone. I'm not supporting the homework-questions. I'm telling that the formula questions never been homework-questions. Do not help him in calcuation. just show what him needs and he will think about that and try to solve it. If him knows what to do, already solved that question then. Take my mind as an idea and discuss about this. $\endgroup$ – user172034 Oct 13 '17 at 20:42
  • $\begingroup$ @JMac Homework policy seems good, did not say a thing about that. I mean the formula questions. You will see that the formula questions are in conceptual physics and never been anything other. It's too normal. Do not help anyone with calcuation. Just show him the true equation to use. $\endgroup$ – user172034 Oct 13 '17 at 20:49
  • $\begingroup$ Believe in me, It won't take your time to show an equation. Now this site will have an aim and you will see that him solved the problem with your equation. If him wants more like calcuation/near to final answer, then it ought to be off-topic. $\endgroup$ – user172034 Oct 13 '17 at 20:53

    $\begingroup$ No one is "kicking" anyone to anywhere. I think AccidentalFourierTransform's answer provides some good insight as to why we don't see providing formulae as a beneficial practice. It is not actually a conceptual question to ask "What formula do I use here?" Formulae are not concepts, they are the application of concepts. You can ask conceptual questions about formulae; but asking if a formula is appropriate is not a conceptual question in itself, it is a question about the exercise. It does take time to provide or verify an equation for someone. $\endgroup$ – JMac Oct 13 '17 at 20:54

    $\begingroup$ But more importantly; people here are volunteers. Many of the volunteers (and especially those who participate in the meta and have been vocal about policies) have agreed that such questions are not in line with the site we wish to be. If we start allowing such questions, the site would become flooded with them. Our members have decided that they do not wish to deal with such questions. I don't blame them. It's not interesting for us to verify or provide formulae for students. It is interesting to discuss underlying concepts; which are the types of questions that are well received. $\endgroup$ – JMac Oct 13 '17 at 20:57

    $\begingroup$ You still seem to be missing the point. "Just allowing formula questions" is essentially the exact same as allowing homework as far as member contribution is concerned. You're essentially saying "Give me every piece of information I need to solve this problem without critically thinking.". The reason I say that is because many of us were not always told the equation to use when doing physics. The point is to research yourself in the textbooks and understand why you are using those formulae. Us telling you which equations to use doesn't help you in the long run. $\endgroup$ – JMac Oct 13 '17 at 21:03

    $\begingroup$ You're still ignoring my main point, and the point of AccidentalFourierTransform's post. Getting the right equation in a situation is generally the hardest part of homework and exercises. Anyone who has taken algebra can substitute values in for the variables and get the solution if given the formula. You won't really learn physics if you are always given the formula to use in each situation. You'll just be doing algebra that gives physical results. In my opinion, it's not "helping" anyone to spend our time checking other peoples work or providing them equations. $\endgroup$ – JMac Oct 13 '17 at 21:09

    $\begingroup$ @Liam Other communities do get spam. Other communities also are allowed to have different policies on homework. Math SE for example, seems more prone to just solving any problem given to them. Engineering SE has similar (though less fleshed out) homework policies to Physics. There are times where a "help vampire" will fill up the new questions with homework questions; and it's really annoying. Quite honestly, I would see no personal value in answering a question by just providing an equation. Good questions make the person answering think as well. $\endgroup$ – JMac Oct 13 '17 at 21:18

    $\begingroup$ @JMac This poster had a similar “what equation should I use” question a couple of days ago, followed by a (apparently now deleted) meta post of the type you have here. It would be more constructive for everyone if the poster worked on editing his/her questions to they fit the guidelines but to each his/her own. There we go: physics.meta.stackexchange.com/questions/10209/… $\endgroup$ – ZeroTheHero Oct 13 '17 at 21:29

    $\begingroup$ @Liam You've ignored me about 20 times when I said that "Check my work" is off-topic for this site. Your question on Kelper's Law is exactly that. Also, the site has an aim as is; that is why we close questions that go against our agreed purpose. $\endgroup$ – JMac Oct 13 '17 at 21:42

"formula questions" could mean anything. If the question is "give me the formula to solve my problem", then the answer is no: such questions are disallowed. On the other hand, if your question is about the physics behind some concept, then the answer is yes: such questions are allowed. Unfortunately, your post is of the first kind.

Note that when it comes to undergraduate physics, knowing which is the right formula to use is usually the hardest part of the problem. Therefore, if someone gave you the formula you are asking for, they would essentially be solving your problem for you. Algebraic manipulations to a formula is usually straightforward, and does not represent a significant part of solving a problem. But knowing which formula to use does.

The policy of this community is: we will not solve your problems for you. We will do our best to help you understand the physics behind the problem, but we will not solve it for you. This is the official policy of this community.

I will not discuss whether I agree or not with this policy. But it is there, and until it is changed, we will have to live with it, like it or not. Try to change your question to comply with this policy, and it will be reopened. For now, it will most likely stay closed.

Note that people have been trying to modify this policy for years. Don't expect it to be changed because of you, and don't expect us to make an exception just this time. It won't happen and you would be wasting everybody's time. The best you can do is to edit your post into something that is on-topic. Asking for a formula is not, and will not be in the foreseeable future, on-topic.

If your concern about this policy goes beyond your particular post, you are welcome to discuss it in general terms, but do note that there are dozens of post here on meta about that. Please read them before making new suggestions. Get used to the idiosyncrasies of the community, and make sure you understand the context behind every decision that has been taken. It will lead to a much more mature and fruitful discussion. Trying to change how an established community works just because you need something from it at a particular moment of your life is truly execrable and just as selfish as it gets. Trying to change it because you care about the well-being of the community is very commendable and we would all be very thankful for such an attitude.

  • $\begingroup$ You say that you admit the conceptual questions. I've already asked a conceptual question also did not mean ''Give me the formula to solve my problem'', ''I doubt this formula, Could you show anohter?''. Really, what you admit then? Is it really too hard to show an equation at least? Everyone might learn easily with that. Okay, you are right at homework troubles. But not right at formula questions. I had put that question to show what i mean. $\endgroup$ – user172034 Oct 13 '17 at 19:58
