Schools Relearning high school math & physics

AI Thread Summary
The discussion centers on the need for a layperson interested in physics to revisit foundational math and physics concepts to advance their understanding. The individual expresses a desire to relearn calculus and physics fundamentals, specifically mentioning the SAVTU equations, which relate distance, acceleration, initial and final velocities, and time. Recommendations for online resources and textbooks are shared, including MIT's OpenCourseWare and books by James Stewart for calculus and Resnick and Halliday for physics. Participants emphasize the importance of self-study, suggesting that older editions of textbooks can be sufficient and that students can focus on relevant sections rather than attempting to cover entire textbooks. The conversation highlights the challenges of self-directed learning and the need for structured resources and exercises to reinforce understanding.

I'm very into physics at a layperson's level, but I find I am not going get anywhere without the math and physics theory to back it up. I took physics, calculus and functions in high school, but that was a looooong time ago. I'm thinking that, in order to advance my knowledge in physics, I'm going to have to "go back to school".

I think I need to brush up on the fundamentals of calculus and the fundamentals of physics (eg. SAVTU equations). Can anyone recommend some good online resources where I can relearn this stuff?

I will look through the PF tutorials, but I think I need a little more than that. I should probably do exercises, etc. I guess I'm thinking of actual online courses but I'm open to suggestions.

Get these lecture notes on mechanics, SR and simple classical (lagrangian) mechanics (w/ exercises AND solutions). I have the set from 2004 ("Old Book"), and thanks to you I've found that some of the chapters have been updated. :)

I'd pick up at textbook by James E. Steward called Calculus.

He has an introductory part and Appendixes for those students who might need it.

Great way to start.

Good luck with everything too!

SAVTU equations? :confused:

When I google on "SAVTU" all I get are pages in Turkish and Czech!
 
James Stewart-INtro to Calculus
R.Serway - Intro to (modern) physics for scientists
 
Youch, 1513 pages and 1184 pages. I think what people forget is that they had courses to set a steady pace for them over the course of 18 months or so. I think I might find those too intimidating for self-study. Maybe something easier to hold while reading, like the Dover Essential Calculus, would be a better place to start.

Also, since you aren't taking courses, if you do get a textbook, you don't need to get the latest edition pushed by the publisher. I really like the 3rd edition of Resnick and Halliday's Physics (not Fundamentals of Physics) in two volumes.

College-level physics textbooks always include far more material than can be covered in a normal course. Publishers don't want to risk losing a potential sale to an instructor whose favorite special topic isn't included.

I don't think I've ever taught a course in which I've gotten though the entire textbook. Usually it's somewhere between half and two-thirds.

Right, an instructor will choose what to leave out and what problems to assign. Without that guidance, I'm wondering how appropriate a big text like that is for self-study.

Why wouldn't they be? You study the sections you want to learn, and do problems in a section until they are boring because they are trivial to you.

There usually is guidance in most textbooks anyways, a section in the intro stating what sections the author typically uses for a 1 term course for example. Or some kind of dependancy thing, which sections are required as pre reqs for which sections. Or marking sections as 'optional' meaning later material doesn't rely on them.


As you mentioned, the latest editions are absolutely not necessary for self study (this is often true when taking a course as well), so used or free books are good options. Calc books tend to not be as cheap as I'd hope in used bookstores probably just based on their size. Discarded old editions can sometimes be had lying around math departments, or university swap shops.

s=distance, a=acceleration, v=velocity(initial), t=time, u=velocity(final)

There's like, five formulae that intertwine these five variables, with which you can solve almost all basic mechnical physics problems.

Sorry, I guess that's changed since my high school days too.

Certainly the variables for initial and final velocities have changed. :D
