Previous PHYS121 courses

Below are Question-and-Answer and some supplemental material postings from previous PHYS121 courses. You should consider these postings to be a resource which may help to answer some (but certainly not all) of the questions that you will have as the quarter proceeds. Some postings may be somewhat out of date, or may refer to days/dates/times/assignments from several years ago.
