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.
A common Assessment Task in HSC Physics is to release a ball bearing from rest on a track inclined at a small angle to the horizontal and measure the time taken (t) to move various distances (d). The average speed is then calculated (v=d/t) and a graph of v-t is drawn. A common mistake is to then say that the gradient of this graph is the acceleration of the ball. Why is this incorrect? How do we determine the acceleration of the ball?
Welcome to Sydney Physics Tutor, my name is Stephen McAndrew. I have taught Physics and Mathematics in independent schools in Sydney and the UK for 38 years. I offer expert individual tutoring to allow students to fulfil their academic promise. I focus on the individual student and prepare structured work to address their particular deficiencies in knowledge and skills and develop these deficiencies into strengths. I use traditional methods of instruction where students write their answers in examination style format and are tested regularly to build their confidence and so develop a love of learning in Physics and Mathematics.
