Introduction About this guide
This book is intended to help you to prepare for your University of Cambridge International A and AS level physics examinations. It is a revision guide, which you can use alongside your textbook as you work through your course and towards the
introduction

end when you are revising for your examination. The guide is split into two main parts. Pages 13 to 130 cover the AS examination. Pages 131 to 287 cover the A2 examination. ●●
This Introduction contains an overview of the AS and A2 physics courses and how they are assessed, some advice on revision and advice on taking the examinations.
●●
The Content Guidance sections provide a summary of the facts and concepts that you need to know for the AS or A2 physics examination.
●●
The Experimental Skills sections explain the data-handling skills you will need to answer some of the questions in the written examinations. It also explains the practical skills that you will need in order to do well in the practical examination.
●●
The Questions and Answers sections contain a specimen examination paper for you to try. There are also two sets of students’ answers for each question, with typical examiner comments.
It is entirely up to you how you use this book. We suggest you start by reading through this Introduction, which will give you some suggestions about how you can improve your knowledge and skills in physics and about some good ways of revising. It also gives you some pointers into how to do well in the examination. The Content Guidance will be especially useful when you are revising, as will the Questions and Answers.
The syllabus It is a good idea to have your own copy of the University of Cambridge International Examimations (CIE) A and AS level physics syllabus. You can download it from:
http://www.cie.org.uk
The Syllabus Content provides details of the facts and concepts that you need to know, so it is worth keeping a check on this as you work through your course. The AS syllabus is divided into six sections, I to VI; the A2 syllabus is divided into seven sections, I to VII. Each section contains many learning outcomes. If you feel that you have not covered a particular learning outcome, or if you feel that you do not understand it, it is a good idea to do something to correct this at an early stage. Don’t wait until revision time!

Introduction
Do look through all the other sections of the syllabus as well. There is a useful summary of the quantities you should be familiar with and their usual symbols and the unit in which they are measured. As you work through your course, you could use a highlighter to mark each of these quantities that are relevant for the topics you have covered.
Syllabus content In the syllabus the AS work is written in ordinary type, whereas the A2 work is written in bold type. The content of the AS syllabus is divided into six sections: I
General physics — Physical quantities and units; Measurement techniques
II
Newtonian mechanics — Kinematics; Dynamics; Forces; Work, energy and power
III Matter — Phases of matter; Deformation of solids IV Oscillations and waves — Waves; Superposition V Electricity and magnetism — Introductory electric fields; Current electricity; d.c. circuits VI Modern physics — Nuclear physics The content of the A2 syllabus is divided into seven sections: I
General physics — Physical quantities and units; Measurement techniques
II
Newtonian mechanics — Motion in a circle; Gravitational field
III Matter — Ideal gases; Temperature; Thermal properties of materials IV Oscillations and waves — Oscillations V Electricity and magnetism — Electric fields; Capacitance; Magnetic fields; Electromagnetism; Electromagnetic induction; Alternating currents VI Modern physics — Charged particles; Quantum physics; Nuclear physics VII Gathering and communicating information — Direct sensing; Remote sensing; Communicating information The main part of this book, the Content Guidance, summarises the facts and concepts covered by the learning outcomes in all of these 13 sections.
Assessment The AS examination can be taken at the end of the first year of your course, or with the A2 examination papers at the end of the second year of your course.
What is assessed? Both the AS and A2 examinations will test three Assessment Objectives. These are:
6
A: Knowledge with understanding This involves your knowledge and understanding of the facts and concepts described in the learning outcomes in all sections. Questions testing this Assessment Objective will make up 37% of the whole examination.
B: Handling information and solving problems This requires you to use your knowledge and understanding to answer questions involving unfamiliar contexts or data. The examiners ensure that questions testing this Assessment Objective cannot have been practised by candidates. You will have

to think to answer these questions, not just remember! An important part of your preparation for the examination will be to gain confidence in answering this kind of question. Questions testing this Assessment Objective will make up 40% of the whole examination.
C: Experimental skills and investigations This involves your ability to do practical work. The examiners set questions that require you to carry out experiments. It is most important that you take every opportunity to improve your practical skills as you work through your course. Your teacher should give you plenty of opportunity to do practical work in a laboratory. The skills built up in AS are developed further at A2. In addition, you are expected to understand how to plan an investigation. Although Paper 5 does not require you to carry out an experiment, the only way to learn the skills required to succeed on this paper is by working hard in the laboratory. Questions testing this Assessment Objective will make up 23% of the whole examination. Notice that more than half the marks in the examination — 63% — are awarded for Assessment Objectives B and C. You need to work hard on developing these skills, as well as learning facts and concepts. There is guidance about Assessment Objective C for AS on pages 100–116, and for A2 on pages 258–265.
The examination papers For security reasons there are now papers for different time zones across the world. The papers are labelled 11, 12 etc., 21, 22 etc., 31, 32 etc. For convenience this book will use Paper 1 for the suite of papers 11, 12 etc.; Paper 2 for the suite 21, 22 etc. and so on. The AS examination has three papers: ●●
Paper 1
Multiple choice
●●
Paper 2
Structured questions
●●
Paper 3
Advanced Practical Skills
Paper 1 and Paper 2 test Assessment Objectives A and B. Paper 3 tests Assessment Objective C. Paper 1 contains 40 multiple-choice questions. You have 1 hour to answer this paper. This works out at about one question per minute, with time left over to go back through some of the questions again.

Introduction
Paper 2 contains structured questions. You write your answers on lines provided in the question paper. In numerical questions, you are given a blank area for your calculation, with an answer cue at the end. The answer cue will remind you of the quantity you are to calculate, followed by a short line for the numerical answer. The unit may or may not be given. Watch out for this. If no unit is given, you must provide it. You have 1 hour to answer this paper. Paper 3 is a practical examination. You will work in a laboratory. As with Paper 2, you write your answers on lines provided in the question paper or in the blank areas provided for tables and numerical work. You have 2 hours to answer this paper. The A2 examination has two papers: ●●
Paper 4
Structured questions
●●
Paper 5
Planning, Analysis and Evaluation
Paper 4 has two sections and you have 2 hours to complete it. Section A consists of structured questions based on the A2 core (Sections I to VI), but may include some material from the AS work. Section B consists of structured questions from Section VII, Gathering and communicating information. All questions must be answered and you write your answers on lines provided in the question paper. Paper 5 consists of two questions based on the practical skills of planning, analysis and evaluation. The paper specifically tests practical skills and consequently the work is not necessarily confined to that covered during the A-level course. As for Paper 4, you write your answers on lines provided in the question paper. You have 1 hour 15 minutes to answer this paper.
