Intro Physics I’d like to learn physics

member 624364

Hello.

I’d like to self-learn physics. basically starting from a zero knowledge background to keep things simple.

I have asked before and some individuals said that it is using your time to learn it once you know calculus? Is this true or should I start learning the basics now so that when I get to more advanced physics say end of high school 1st year physics undergrad that then knowing calculus would be useful?

Currently I have not yet gotten to learning calculus, I am finishing algebra and starting pre-Calc.

Would it be most efficient and beneficial to dedicate my time currently to simply learning calculus and then to learning physics? I am simply looking for the most efficient route so I don’t waste my time learning from a basic maths physics book that I will later down the line learn once again but with a calculus emphasis or something.

Also, as a side note, does this same rule apply to chemistry and biology? I would like to learn them as well but maybe not to as high a degree, say end of high school level.

Forget end of high school. You'll need calculus even for starting physics of high school level. That's what makes it difficult for me to recommend any book. Let's see what others recommend.

But you should give greater part of your time in calculus and Trigonometry. Those should be at your finger tips. Otherwise you'll face serious trouble later.
 
what is important is the subject matter. the presentation is less important, though i guess maybe more valuable when you are just getting started out. the class that made the most impact on me was discrete math because it taught me the language to read my calculus textbook the next semester. i.e. set notation, logic and knowledge of how to do proofs. i am largely self taught though i took Calc I and II. i ignored the professors and just read my textbook, and still did well on exams and homework.

i find that caffeine helps with motivation (and probably other things ... but i take high doses which cannot be healthy). at your age you could probably drink tea and it wouldn't hurt your brain development. developing a ritual of self study tied to tea drinking could work. that's what i do now, except with coffee, but i'm an adult. maybe you don't need that, it's just a suggestion based on what works for me for self study.

there's a lot of physics and math you can learn on the internet, but i think it would be hard to do without a good textbook. internet explanations are often not complete in my experience.
