General Physics II

Welcome to the web-page for the 2017 summer semester General Physics II (PHYS 122) course. Here you will find announcements, homework assignments, and exam information. Let me know if you have any questions. My contact info can be found in the syllabus.

Office hours: MTWR 10am--11am, or by appointment; please e-mail me.

For each chapter I will post keywords that I would like you to Google, and/or search for on YouTube, and familiarize yourself with them. Such non-linear learning mode---different from the usual linear mode of reading sections in a book in the order they come in---might help you to better understand and remember the material.
