Module One
MEASUREMENTS AND UNITS
Introduction
Physics is connected to our everyday life in thousands of ways. We measure and estimate several quantities like length, time, mass and speed many times during our day-to-day routine, but these quantities are also important when we try to understand the technology around us. The first module describes different ways to measure and calculate these quantities accurately.
This Module should be read in conjunction with the Programme of Study.
The Programme of Study lists the Topics that are in the Module and gives you the relevant page references to your coursebook. This Module aims to give you more direction as you work through the various topics. It will aim to highlight the most important items in the Topic, as well as areas that need particular care. It will also point you towards the Resources, available through CANVAS, that you should be using, as well as listing the coursebook pages to be worked through.
It is not enough to read the text; you should be able to apply your knowledge. Please do as many questions in the coursebook as possible: those on each double-page spread, and the check-up questions at the end of the chapter. A good problem solving routine will help you to finish the exam papers in time. You can check your solutions using the answers on page 320.
Remember to double-check with the Syllabus (the Section number is listed on your Programme of Study) that you cover all the items that you need to.
