Forms of Energy Volume 5 This book is the product of my experience of teaching Physics to high school and sixth form students for over twenty-three years. Throughout that time, I found my students greatly benefited from having comprehensive notes; this enabled them to revise and consolidate knowledge of complex subject material. Originally, the detailed notes were given to students as class booklets. With time, the notes have grown organically into this book. It contains key learning points in accessible, student-friendly language. The videos are designed to engage and challenge students of all abilities, especially those who wish to go onto further education. It promotes explorative thinking and allows students to make accelerated progress.
