What is the difference between these Physics courses?

High school physics: a general introductory course that covers the fundamental concepts of physics, like motion, forces, energy, waves, and electricity (good starting point if you have no background in physics)

High School Physics - NGSS: similar to high school but applies it to real-life scientific practices. 

AP College Physics 1 & 2: These are advanced, calculus-based courses that prepare students for college-level physics. (if you have a solid foundation in high school physics) 

Physics Library: is a collection of resources. 

UP Class 12 Physics and Bridge Course Class 12th Physics: specific to high school level math I would put this between high school and AP college. 

I would suggest you look around each topic. 

1. High School Physics/High School Physics - NGSS

2. UP Class 12 Physics / Bridge Course Class 12th Physics

3. AP College Physics 1 & 2

4. Physics Library (remaining topics) 

If one seems to easy move to the next one but if one seems too hard and you need a refresher you can go back to the previous course. But, don't forget to look at the topics for each of them.
