PHYS 10 - Lecture 1 - What is Physics? Models, Units, and Learning Physics in Age of AI

In this first lecture in 30-lecture set, we set the stage for the whole course: what physics is (and isn’t), how scientists use models to describe nature, and how we communicate measurements using physical quantities and units. We also do several practical unit-conversion examples—the kind of skill you’ll use constantly in problem solving. Topics in this lecture: • What physics studies and how this course is organized • Models vs. theories vs. laws (and why the differences matter) • Physical quantities, SI base units, derived units, and prefixes • Unit conversion examples (including everyday speed units) • How to use generative AI to learn physics (without letting it short-circuit your learning) Textbook (free, online on LibreTexts): https://coaphys.xyz/phys10book Recommended reading: Chapter 0 (overview + physical quantities/units) ────────── Lecture 1 of 30-ish in "Physics 10 in 30 Lectures" 00:00 - Lecture 1 Intro 02:32 - Chapter 0 Overview 10:28 - Models, Theories, Laws 19:42 - Intro to Physical Units 29:32 - Unit Conversion Examples 47:55 - Generative AI and Learning Physics ──────────
