Physics becomes manageable when facts, laws and equations are understood as parts of one connected system. Explicit Physics was written to help learners make that connection: to observe a situation, identify the governing principle, select an appropriate relationship and communicate a defensible answer. It is designed primarily for candidates preparing for UTME/JAMB, and also serves senior secondary students, teachers and tutors who need a rigorous, examination-focused reference. The book follows the major themes prescribed for senior secondary and UTME/JAMB Physics, from measurement and mechanics through thermal physics, waves, optics, electricity and magnetism to modern physics, electronics, fibre optics and lasers. Each chapter develops concise teaching notes, definitions, laws and formulae, supported by diagrams, worked examples, examination notes, common traps and quick-revision prompts. Revision questions are arranged under the syllabus-aligned subsection in which each concept is taught. This allows students to recognise recurring patterns, compare related methods and correct misconceptions before they become habits. Historical examination items have been retained where useful; damaged typography, dated notation and genuinely ambiguous wording have been clarified without changing the physics being tested. To use the book effectively, study a subsection, reproduce its essential formulae and conditions from memory, then attempt the associated questions without looking at the answers. In calculations, show the formula, substitution, units and final choice. In conceptual items, name the governing law and explain why the alternatives fail. The consolidated Answers and Explanations section should be used for diagnosis, not merely for checking letters. Teachers and tutors may use the chapter sequence for classroom revision, the question banks for timed practice, and the explanations for feedback and remediation. Students should keep a record of errors by topic, revisit the relevant lesson, and retry missed questions after a short interval. This cycle of understanding, practice, correction and recall is more reliable than memorising isolated answers. This first edition aims to be comprehensive without becoming needlessly bulky. Its two-column layout, focused explanations and extensive question bank are intended to make revision efficient while preserving the depth needed for unfamiliar problems. Our hope is that Explicit Physics will improve examination performance and, more importantly, develop the disciplined reasoning through which Physics becomes a coherent way of understanding the physical world.
