project at the University of Cambridge that develops understanding and confidence through problem solving in the physical sciences, by combining accessible and concise print resources with a state of the art online study tool. This book is a co-publication between Periphyseos Press/Isaac and Cambridge University Press. 2 books in 1: ESSENTIAL PRE-UNIVERSITY PHYSICS helps you master the concepts of physics in pre-university courses (including A Level, IAL, IB and the AICE Diploma). Use the skill sheets to practise applying fundamental principles of physics to a range of situations, beginning with manipulating the essential equations. DEVELOPING PROBLEM-SOLVING SKILLS builds the problem solving fluency needed for physics and engineering at university. All problems can be answered on the Isaac online platform. Registration is free and gives both students and teachers personalised support through a sophisticated online marking system for all problems and a section-by-section archive of video lessons.
