Rules regarding home-work questions

Sometimes there are questions in one's mind which he needs answering but those are just confusion in his own mind not any homework question or any question he read in a book. But to explain the question better that person uses diagrams and examples, and all of the community declares it a homework question.

I suggest there should be a simple rule to decide if that question is acceptable or not.

1. If the questions gives a problem to the community and asks others to solve it for him it is unacceptable and considered as homework.
2. If the question asks explanation of the underlying physics in a case and the user makes an effort by himself to understand it is considered a "physics problem" not a "homework question".

Examples:

1. Velocity of satellites greater than required velocity
This question discusses a case in which velocity of satellites gets greater than required velocity and asks what happens and why?
This question is definitely not a homework question.
2. A problem of thermodynamics
The text of the question goes like this:

A rigid tank contains a hot fluid that is cooled while being stirred by a paddle wheel. Initially the internal energy of the fluid is 800KJ, during the cooling process, the >fluid loses 500KJ of heat, and the paddle wheel does 100KJ of work on the fluid: >determine the final internal energy of the fluid, neglect the energy stored in the paddle >wheel Can you help me solve this?

In this question the user asks a physics problem from book or somewhere else and expects an answer which is worked solution and calculation.
It is clearly a homework question.

• We already have a pretty clear boundary, if a question is clearly asking for conceptual help, it is not homework. The name "homework" is misleading, though. Also, the policy explains how closed questions can be improved to be conceptual -- closing is not the end of the line for a question, just a pit stop. Sep 25 '14 at 12:06
• I have read the policy before posting this. Does the meta discussion ever change policy? Sep 25 '14 at 13:43
• Yes, it does, but this is a policy that has had months of debate and improvements put into it, so there's very little chance of it changing without much more discussion to back the change. (Other meta threads like the one Jim linked to are doing this now) Sep 25 '14 at 16:43
