This may be an odd post, but I'm writing a short film in which a college student is having some trouble with a general physics course. Having never taken physics myself, I'm looking for sample dialogue to use in a particular scene. What I need help with is the professor's dialogue in this scenario: After class, the student listens to her professor conclude his explanation of how to solve a particular physics problem, or maybe he explains a way of thinking that makes clear how to solve an entire host of problems. The student's response is something like "ahh, now that makes sense." It is mere days before finals week, so the professor's explanation must be about something beyond simple physics principles, but it cannot be more advanced than what is taught in an introductory physics course. Any and all suggestions would be of great help. Thanks!!
