The objective is to provide the students with a solid knowledge of the main concepts of General Physics, with some outline given to modern physics. These concepts are fundamental for the deep understanding of many of the phenomena in chemistry and in the involved instrumentations.
The student will be able to analyze and resolve physics problems of medium/easy level. The student will have to communicate in an effective and appropriate way his knowledge.

None

The course is offered in the traditional way, with lectures and collective exercises. Slides, and occasionally videos and multimedia applications are used to assist the lectures. Many hours are devoted to problem solving. Several homeworks are proposed to the students in order to encourage their participation. Lectures offered in video/remote in case of COVID-19 emergency.

Midterm written test (optional, 6 exercises/questions - 40 min) . Final written examination, or second term test, with exercises and questions on theory, open or multiple choice, covering all the remaining topics of the course. The final written test consists of 5 groups of exercises/questions to be completed in about 70 min. Mandatory final oral test, bound to scoring at least 16/30 in the written test. The grade is the arithmetic average of the notes obtained in the tests performed.

The student has to demonstrate a solid knowledge of the main concepts of General Physics (and some of modern physics), and the capability to apply this concepts for the understanding and resolution of simple scientific problems in physics. The student is required to be able to communicate in an effective and appropriate way his knowledge and his analysis of the physics problems addressed.
