consider closer alignment with AP physics 1

https://apcentral.collegeboard.org/courses/ap-physics-1/course?course=ap-physics-1

for AP Physics 1 add:
Simple Harmonic Motion (you are doing this, but you need to change up some vocab.)
Torque and Rotational Motion (You have nothing for this section)

AP Physics 2 looks like too much work for now
