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.

Rules of Practical Work:

1. The enrollment of students in groups (of two or three students) is done in the first week of classes, making the students aware of the timetable for carrying out the practical work.
2. Four practical assignments will be carried out:
   2.1.Experimental measurement of the acceleration of an object on a frictionless inclined plane, using an inclined air table;
   2.2. Calibration of a dynamometer and experimental assembly of a system of concurrent forces in balance using two masses, a dynamometer and a graduated scale for angle measurement;
   2.3. Experimental determination of gravity acceleration using a gravitational pendulum;
   2.4. Experimental determination of the moment of inertia of: a rotational device, point masses and a cylinder.
3. Delivery of a pre-report is a necessary condition for access to the work laboratory. (Note: The pre-report can be found in the support material accessible on the course page, hosted in the Moodle of ISEC).
4. Doubts about the practical work to be carried out and in particular about the preparation of the pre-report must be clarified in advance and in good time with the course teacher.

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.
