Newton`s Second Law.
... First of all, let us deal with a common mental mistake made by beginners. It is perhaps tempting to read Newton’s second law as a literal identification of force with mass times acceleration. This is not the way to think of it. Think of it as follows. You are in the lab. You have set up an experimen ...
