# Module Overview

### Physics for Health Science

The aim of this module is to provide the student with an understanding of the principles and the application of physics in health care sciences.  The student will develop an understanding of key Physics principles and concepts and apply this knowledge to biomedical and health aspects of the human body.  The student will understand Physics concepts, perform calculations, and solve numerical problems, which relate to the human body.  They will develop an understanding of the principles of operation of relevant equipment, instrumentation and technology routinely used in health care environments.

This is a broad module designed for health care science students in biomedical science, nutrition and dietetics, public health nutrition and optometry.  Students will develop an understanding of the application of Physics principles in several topics including mechanics, electricity, magnetism, sound, properties of matter, heat and temperature, and modern physics.  Emphasis is placed on the relationship between natural sciences and health sciences.  It is assumed that students have no prior learning in this subject.
