# Overview

Painless Physics is a comprehensive study aid for high school Physics. It covers topics such as motion, Newton's Laws, optics, energy, waves, forces and astronomy, and uses a conversational, informal teaching style. Every topic is explained in detail, with sample questions and fully worked solutions to work through. It also contains all the practical tips, tricks, and advice picked up by myself and students.

"I also purchased your physics book and it is also fantastic" ...Laura, student

"I have two of your books for my children in Year 9 and 10. Not a C Minus and Painless Physics...Your books are fantastic. " ...Julie, mother
