What are the concepts in Physics and Mathematics that students find difficult? In this blog I will post tutorial sheets that I hope will stimulate thinking and so broaden the knowledge and understanding of students allowing them to write thorough examination responses. Tutorial sheets, structured to assist student learning, will be posted on IB SL and HL Physics syllabus topics as well as the general HSC topics of relativity, electromagnetism, mechanics, thermodynamics, quantum physics and calculus. The overall purpose of these pages is to encourage and promote learning in Physics and Mathematics and so open new horizons in learning.
