Física Geral

The following basic knowledge is recommended:

• Secondary school physics (10th and 11th grades);
• Differential and Integral Calculus, acquired in the Curricular Unit of Calculus I, of the 1st Semester of the 1st Year of the Degree.

The Curricular Unit (CU) consists of 3 types of classes:

1. Theoretical classes, in which the contents of the CU program are exposed.
2. Problem solving classes, in which exercises are solved by applying the knowledge exposed in the theoretical classes.
3. Laboratory classes, in which experiments are carried out within the scope of the CU syllabus.

Inappropriate behavior that in any way compromises the normal functioning of the class is not permitted, the use of cell phones in any typology of classes, and the use of tablets and computers is not permitted in theoretical and theoretical-practical classes. Students who use, or attempt to use, any of the aforementioned devices, or who in any way disrupt the normal functioning of classes, will be expelled from classes and will be marked as an unjustifiable absence.

This course aims to provide students with knowledge in some areas of physics with particular im-portance in the field of Biomedical Engineering. The afore mentioned knowledge is fundamental to a better understanding of some biological processes as well as the principles of operation of several medical and biomedical instrumentation for measuring biological parameters. Thus, students should acquire skills in the fundamental principles and laws in the different areas of physics taught, learn to apply the acquired knowledge in concrete practical situations, as well as interpret and discuss the physical meaning of numerical expressions and results of laboratory experiments.
