Semi-retired after 42 + years teaching in the UK and NZ . . . Auckland NZ based member of the UK Institute of Physics, hence kiwiminstp. . . . Most resources here are short extracts from Simply Physics which is the name of the course material my wife & I have developed for teaching NCEA Physics to suit our style and clientele. We have made these extracts available to support colleagues teaching high school Physics in NZ but I hope that they may prove useful to others around the planet.
