Good job. There are some places where simple improvements can be made. Page 3. "Tension has no direction". False. Tension is a force vector and it must have a direction, the direction is parallel to the string or chain. Page 3. F net should say F normal for calculating kinetic friction. Page 6. It would be worthwhile to state that momentum is a vector quantity and obeys the rules of vector addition and subtraction (unlike kinetic energy).
i don't think there's anything else i used but i think that's it. if you want to use latex more easily, you can enter an equation into desmos and copy paste it - it will convert it to desmos. for stuff like aligning you should probably like search a tutorial ( i don't think i can explain it well )
