Learning Objectives

Physics and Biomechanics
The purpose of the Physics module is to teach basic physics and mathematics with simple applications to biomedical problems. The homogeneity of the preparation for all students is to be obtained in view of the specific knowledge required in the continuation of the Degree Course. In particular, the student must acquire knowledge of some basic laws and physical techniques for the understanding of physiological, biological and medical processes and will have to learn basic concepts useful for the correct use of the instrumentation used in the professional field.

Course Structure

Physics and Biomechanics
Traditional lectures, with the support of slides and audiovisual tools. At the end of the lecture, ample space is given to the comment on the discussed topics.
