Introduction

Physics 222, Elements of Physics II, Summer 2024, is an asynchronous online introductory physics class with laboratories.  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 9 weeks in the Summer 2024 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

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.

AI chatbots

Asking questions and exploring different aspects of the topics covered in the class material is one of the best ways to learn physics.  You can use AI chatbots as a helpful tool for this purpose, as they can give you answers, explanations, examples, and more.  Try to think of good questions that interest you, challenge you, or help you review what you have learned.   Then ask an AI chatbot and see if its answers make sense or not.

You can also share the answers you get from the AI chatbots with your classmates in the discussion forum. This will make this activity more engaging and collaborative. Everyone can comment on the answers and discuss whether they helped them understand the concepts better or not.  You can also learn from each other and exchange different perspectives and insights.  Please remember to identify which answers are generated by AI chatbots and which are your own.

Using AI chatbots to ask and answer questions can be a fun and effective way to deepen your knowledge and curiosity about physics.  I hope you enjoy this activity and benefit from it.


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.
