Objectives
THE COURSE HAS THE OBJECTIVE OF PROVIDING THE STUDENT WITH A SOLID FORMATION IN THE FIELDS OF MECHANICS AND THERMODYNAMICS.

KNOWLEDGE AND UNDERSTANDING:
THE TEACHING PROVIDES THE BASIC KNOWLEDGE OF NEWTONIAN MECHANICS AND ITS MAIN APPLICATIONS IN REFERENCE TO THE DYNAMICS OF A SINGLE POINT, OF SYSTEMS OF MATERIAL POINTS AND OF RIGID BODIES. THE STUDENT ALSO ACQUIRES THE BASIC KNOWLEDGE OF ONDULATORY PROCESSES, THERMODYNAMICS OF EQUILIBRIUM PROCESSES AND THE PHYSICS OF IDEAL FLUIDS. THE PROVIDED KNOWLEDGE ALLOWS THE STUDENT TO FRUITFULLY FOLLOW THE INSIGHTS ON THESE TOPICS THAT ARE PROPOSED IN THE FOLLOWING OF HIS STUDIES.

APPLYING KNOWLEDGE AND UNDERSTANDING:
THE TEACHING AIMS TO OBTAIN THAT THE STUDENT BECOMES ABLE TO APPLY THE ACQUIRED KNOWLEDGE IN A CORRECT WAY, FOLLOWING THE SCIENTIFIC METHODOLOGY, IN ORDER TO FACE AND SOLVE PROBLEMS REGARDING MECHANICS AND THERMODYNAMICS. AT THE SAME TIME, HE ACQUIRES A DEEPER UNDERSTANDING OF PHYSICAL REALITY. FURTHERMORE, THE STRUCTURE OF THE COURSE, BY COMBINING FORMAL ASPECTS WITH PRACTICAL APPLICATIONS, TENDS TO DEVELOP IN THE STUDENT AN EFFECTIVE LEARNING METHODOLOGY.
Prerequisites
IT IS USEFUL THAT THE STUDENTS HAVE A WORKING KNOWLEDGE OF ELEMENTARY ALGEBRA, EUCLIDEAN GEOMETRY, TRIGONOMETRY AND ELEMENTARY FUNCTIONS ANALYSIS. ALSO, A GENERIC KNOWLEDGE OF CLASSICAL PHYSICS IS USEFUL, AND AN ATTITUDE TO IN-DEPTH AND LOGICAL REASONING.
THE KNOWLEDGE DEVELOPED IN THE COURSES OF ANALYSIS I, GEOMETRY AND CHEMISTRY ARE NOT ESSENTIAL. HOWEVER, THIS KNOWLEDGE HELPS IN A BETTER UNDERSTANDING OF THE TOPICS OF GENERAL PHYSICS I. THEREFORE IT IS SUGGESTED THAT THE STUDENT FOLLOWS SUCH COURSES WITH PROFIT.

Teaching Methods
LESSONS, NOT ONLY ABOUT THEORY BUT SUPPORTED BY APPLICATIONS OF GRADUALLY INCREASING DIFFICULTY. STIMULATED DISCUSSIONS BASED ON THE SEARCH FOR ERRORS AND/OR REASONING, TO MOVE TOWARDS A DEEPER UNDERSTANDING OF THE CONCEPTS. ONGOING CHECKS ARE ALSO SCHEDULED TO TEST THE CAPACITY DEVELOPMENT.
Verification of learning
FINAL EXAMINATION CONSISTS IN A WRITTEN TEST FOLLOWED BY AN ORAL TEST (ONLY IF THE OUTCOME OF THE WRITTEN TEST EXCEEDS A GIVEN THRESHOLD VALUE). BOTH THESE TESTS ARE STRUCTURED TO MEASURE THE REASONING CAPABILITY OF THE STUDENT IN TOPICS INVOLVING CLASSIC MECHANICS AND THERMODYNAMICS. BESIDES, IT IS ALSO CONSIDERED IMPORTANT THE VERIFICATION OF THE KNOWLEDGE OF THE SCIENTIFIC METHODOLOGY.
TO AN EXAMINATION, IN WHICH THE WRITTEN PART CONTAINS AT MOST SOME IMPERFECTIONS (BUT NOT CONCEPTUAL ERRORS) AND THE ORAL PART IS AT THE SAME LEVEL, IS GIVEN THE HIGHEST MARK, I.E. 30/30. IF THE STUDENT ADDS A CORRECT LANGUAGE AND A VALUABLE LOGICAL SETTING THEN IT IS USUALLY ATTRIBUTED ALSO THE "LODE".
THE NUMBER OF CALLS EVERY YEAR IS DECIDED BY THE AREA COUNCIL.

More Information
AT THE BEGINNING OF EACH ACADEMIC YEAR, THE GRADUATE PROGRAM ORGANIZES ADDITIVE LESSONS TO SUPPORT STUDENTS WHO HAVE REPORTED INSUFFICIENT OUTCOMES AT THE PRELIMINARY ENTRANCE TEST. THESE LESSONS PROVIDE BASIC PHYSICS AND MATHEMATICS NOTIONS IN ORDER TO STRENGTHEN THE STUDENTS IN TACKLING THEIR STUDIES.
