## Description

A significant amount of the National Physics syllabus involves the solving of numerical problems. The object of this book is to provide sets of simple graded exercises which require the use of formulas mentioned in the syllabus.

The sets of exercises are designed to be attempted immediately following the introduction of the theory or for homework. Although the formulas are given in the examination papers, only by practice will you develop the facility to recognise a problem and solve it.

Detailed answers are included. In some cases the solutions can be obtained via different pathways but should agree in the end with the answers provided.
