Introduction

Physics 222, Elements of Physics II, Summer 2026, is an asynchronous online introductory physics class with laboratories. 

The class material, which I have designed to promote self-study, spaced learning, retrieval practice, and practice testing is mostly text based.  You have to study this material.  As the instructors, I and the lab instructors are your learning facilitators.  We provide you with the learning materials, help you stay on track, and also help you to overcome obstacles.  The course structure is tailored to provide ample individual assistance and feedback.

Physics is not a a collection of formulas that you can remember.  Classical physics consist of a few principles that you have to understand conceptually.  Once you understand them, you can apply them to analyze various situations.  Some concepts can be expressed in terms of mathematical formulas.  But to really understand them, you also have to be able to express them in words.

To become familiar with the course layout and all the course requirements, please start with these steps.

Physics 222 is a 4 credit hour, asynchronous online course taught over 7 weeks in the Summer 2026 semester.

A traditional, face-to-face lecture based course would require students to attend a 50-minute class meeting three times every week and at least ten 2 hour and 40 minute lab/recitation sessions.  In addition, students would be expected to review their class notes, read the textbook, and complete homework assignments.

You are expected to invest an equivalent amount of time in this class.


Class structure

Spaced learning:

There are 10 modules.  Each module is divided into two parts.

Self study: (Read and Think)
You have to study the material linked on the schedule.  This is the material the assignments and tests refer to. 

Retrieval practice

Practice testing

Leveraging AI for Mastery

After you have completed a module, review the summary slides for this module under "Modules" on Canvas.  They offer some additional problems to test your understanding.

Note: I strongly recommend submitting earlier than midnight on the due date and not waiting until the last minute.  You can submit all homework assignment multiple times.  Submitting early allows you to ask questions and get feedback if your first answer was incorrect, and it allows you to help other students once you have arrived at the correct answer.
If you need more help, attend the office/tutoring hours of the instructors.  They are offered at various time throughout the week.  You can attend the office/tutoring hours of any instructor.


Summary:

The online material is my contribution to the class.  It covers all topics that may appear on homework assignments and tests.  Example problems are worked out in the online material.  The textbook presents the same material but expands on some aspects of it.  It is always beneficial to go over new material more than once.  Different presentations are better suited for different audiences.
