Introductory Physics Introductory Physics is a high school physics course that builds foundational concepts using algebra-based problem solving and structured review. Students move through core topics such as motion, forces, energy, and waves, working through explanations and practice that reinforce each concept. The course is designed to focus on essential material without requiring advanced math, making it accessible with a solid Algebra I background. The writing is straightforward and supported by clear diagrams, helping students follow how the concepts connect. Lessons also include historical context and applications, giving students a broader sense of how physics developed and why it matters. This course fits naturally into a standard high school sequence. It works especially well in a “physics first” approach for 9th- or 10th-grade students. It can also be used later, with optional chapters that extend the material for students who want additional challenge. Digital resources are included to support the course. These provide quizzes, exams, answer keys, and planning tools such as a daily lesson list and sample schedule, all accessible for ongoing use. This structure helps students build understanding steadily, so concepts hold together rather than feel like a series of disconnected topics.
