Lecture note on motion graphs

This is something to fill in the gap in OpenStax coverage I found last semester, motion graphs. Other textbooks I have used before have a section or a subsection dedicated to this topic, which seems to be missing on OpenStax University Physics Volume 1.

So, this is the note written to cover the gap (may need to revise a little in the future, after lecturing on additional examples).

Spring 2022 lecture videos posted

I finished processing recorded virtual class sessions from Spring 2022 (for Physics 4A and Physics 4C) and posted them on our YouTube channel (https://youtube.com/c/CoAPhysics). As usual, they are added at the end of the existing playlists (Physics 4A playlist and Physics 4C playlist) and moved around as I prepare for the new semester (the videos occur roughly in the order they appear in the course LMS site).

Oh, I guess this means the Physics 4C playlist will remain in that order for some time, as I am working on Physics 4A and 4B material for the upcoming semester.
