Of course. If the question was to ask about basic physics, there's plenty of help. However, if shaky physics is being used to somehow extrapolate into some speculative ideas, then that's a different matter entirely.
Many members here are often advised to try to learn and establish their understanding of basic physics. In fact, this is something they'll learn very quickly after a few posts. They also learn that they'll better get the foundation right in the first place before trying to build something on top of it. That, in itself, in a valuable lesson to be learned in this forum.
