Syllabus for University Physics 212

The table below shows the sequence of topics we will cover in this course. The syllabus is slightly tentative -- we may occasionally move ahead or fall behind.

In the table below, the listed reading assignments are from Halliday, Resnick, Walker 8th (or 7th) edition. The syllabus is also available as an excel spreadsheet
