Module Overview

Physics 1

This module provides a foundation in four key areas of Physics - Mechanics, Properties of Matter, Heat & Temperature, and Waves. Upon successful completion of this module the student will also have an understanding of the role of physics in other scientific disciplines. The module also aims to develop an appreciation for the scope of these areas of specialisation, their application to their programme area of expertise and an awareness of current developments in these fields.
