The step from GCSE to A-level physics can be daunting. This textbook is designed to help students achieve that transition. Physics syllabuses have changed considerably in recent years, with the emphasis now placed on understanding and applying key concepts. All A-level physiscs syllabuses have a core of common topics and this book is built around these core studies. The book also reflects the importance that is now placed on electronics as a major feature of all A-level physics courses. The book covers the latest syllabuses of each Examining Board and it is organized into eight major sections to reflect these syllabuses. Special attention has been given to making the book highly visual and readable.
