The author originally registered this account to write novels and experience different lives through fiction. But it turned out the author couldn't imagine them at all. So the author decided to gather material from work and practice writing little by little. The author is a middle school physics teacher, and would like to share with everyone some insights into teaching physics, summaries of concepts, ways to solve middle school physics problems, and concepts found in textbooks as well as those not covered in them but likely to appear on exams.
