1. Who is Dinesh Amarathunga?
Dinesh Amarathunga is a renowned Sri Lankan physics teacher and author. His books are specifically designed for students sitting for the GCE Advanced Level (Local) Examination in Sri Lanka (under the National Institute of Education, NIE syllabus). His work is known for:
- Exam-focused content – strictly aligned with past paper patterns.
- Step-by-step problem-solving – breaking down complex calculations.
- Theory + MCQ + Structured + Essay – all in one volume.
- Sinhala medium – primary medium, though some books have bilingual or English editions.

For a review caption:
⭐⭐⭐⭐½ (4.5/5)
Product: Dinesh Amarathunga Physics Unit 02 – Mechanics
Best for: Students who hate theory and love practice.
Warning: The first 10 questions will humble you. Stick with it. The step-by-step solutions in the back saved my grade.
Where to buy: Local bookshops (K.V.G. or Samudra) or PDFs from EduLanka.
#PhysicsBookReview #ALSuccess #DineshAmarathunga Exam-focused content – strictly aligned with past paper
Volume 1 – Mechanics & Properties of Matter
- Key topics: Vectors, kinematics, Newton’s laws, friction, work-energy-power, circular motion, gravitation, rotational dynamics, elasticity, fluid statics/dynamics, surface tension, viscosity.
- Unique strength: Diagrams with real-world examples (e.g., why a car skids, how blood flows).
- Problem style: Starts with simple numeric problems, progresses to exam-level combined concept problems (e.g., friction + circular motion on banked tracks).
Volume 4 – Modern Physics & Revision
- Atomic physics: Bohr model, spectra, photoelectric effect, X-rays.
- Nuclear physics: Binding energy, decay law, half-life, fission/fusion.
- Relativity (intro): Time dilation, length contraction, mass-energy equivalence.
- Solid state physics: Band theory, conductors/semiconductors/insulators.
- Revision section: Topic-wise past paper classification (last 10–15 years) with fully solved answers.
Step 2: Active Note-Taking
Do not read passively. Keep a separate notebook. Every time you encounter a blue definition (core concept), write it verbatim. Every time you see a green example, cover the solution and attempt it yourself first.
Physics MCQ Bank (3 volumes)
- Organized by unit.
- Each question has a detailed explanation – not just the answer.
- Includes “tricky” MCQs where common mistakes are analyzed.
- Tip: Use Vol.1 after finishing mechanics, Vol.2 for waves+optics, Vol.3 for electricity+modern.
C. Syllabus Mapping & Exam Targeting
Every chapter begins with a box clearly stating which sections of the NIE syllabus are covered. Additionally, Dinesh Amarathunga physics books often include references to past A/L questions, marking which year a specific problem type appeared. This exam-oriented approach ensures no time is wasted on out-of-syllabus content. Sarasavi Bookshop (Nugegoda
2. Exam-Centric Data Interpretation
Sri Lankan A/L physics has shifted toward data-analysis questions (graphs, tables, experimental set-ups). Amarathunga’s books dedicate entire chapters to "Graphical Methods" and "Estimation & Approximation"—skills most other textbooks ignore.
