There are a lot of questions that have totally incorrect premises, ask for "a formula" for something where no such formula exists (e.g. "given the gravitational acceleration, what is the formula for position?"), or don't even make syntactic sense.
Several times, I've responded to these questions with an answer that directly addresses what the OP might have been thinking about. Here's an example. I notice the following things.
- Nobody else ever does the same thing: either they post a comment saying the question is bad, or occasionally they post an extremely long answer that beautifully generalizes OP's question into something that makes physical sense, and answers that question using some very high-powered math. (I don't do this because I don't think it would help the OP in any way.)
- Nobody has ever given me any feedback, good or bad, on any such answers I've written.
Am I committing a huge faux pas by shooting out these short, two-sentence answers? Is it better for the site to write those answers in a comment instead?
