Basic math skills are required (basic notions of algebra and trigonometry, function concept, straight line properties, parabola and polynomials, exponential functions and logarithms, trigonometric functions, notions about vector algebra and manipulation of Cartesian coordinates and Polar) and basic descriptive statistics, which are only briefly summarized at the beginning of the course. No prior knowledge of Physics is required, though useful.

The exam consists of a final written test in thirty-five. The exam ensures the acquisition of basic theoretical knowledge provided during the course and the ability to apply them in solving problems. The written exam consists of 8-10 questions, of which two are open, including questions about theory and simple exercises that cover the entire arena of the program.

Knowledge and understanding skills.

The student should acquire basic knowledge in the main fields of Classical Physics; Acquire the ability to analyze phenomena of biotechnology interest by identifying the physical parameters that control them, to understand the constraints on the evolution of such phenomena dictated by the laws of Classical Physics.

Ability to apply knowledge and understanding.

The student should acquire autonomy of judgment in choosing the quantities useful for the quantitative description of biological and medical phenomena, and in choosing the hypotheses about their relationship, and then developing the ability to build a simple physical model of the problems in question. It should also acquire adequate skills and tools to communicate and justify such choices.

The course provides a basic introduction to the main concepts of Classical Physics. It is articulated in sections:

The slides used by the lecturer are partially made available to online students on the e-learning website of the University. The exercises carried out by the teacher are equally available online in the form of reasoned exposure. Students are required to use one or more monographic texts on course topics.

The course includes frontal classroom lessons (40 hours), intercalated by exercises (12 hours) in which exercises are applied that apply the knowledge of the lesson learned theory. The exercises are performed on the chalkboard by the trainer, following a discussion of appropriate strategies to solve them. Students must have a scientific calculator available to follow the exercises.
