	Objectives
	THE CLASS AIMS TO PROVIDE ELEMENTS OF CLASSICAL MECHANICS AND Acoustics, WHICH ARE RELEVANT TO ENGINEERING, PARTICULARLY WITH REGARD TO THE ACQUISITION OF SCIENTIFIC METHODOLOGY, AND IN ORDER TO PROVIDE THE PHYSICAL BASIS FOR THE STUDY OF HIGHER LEVEL CLASSES. Expected results KNOWLEDGE AND UNDERSTANDING: The student must learn the fundamental elements of Mechanics and Acoustics, with particular care to vectors, kinematics, dynamics and statics of mass point, systems of mass points and rigid body, vector fields, acoustic field. ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING THE STUDENT MUST BE ABLE TO OBTAIN A SUFFICIENT UNDERSTANDING IN ORDER TO APPLY HIS KNOWLEDGE TO solve PROBLEMS OF CLASSICAL MECHANICS AND Acoustics. MAKING JUDGEMENT THE STUDENT MUST DEVELOP CRITICAL THINKING AND INDEPENDENT JUDGMENT TO SOLVE PROBLEMS SUCH AS THOSE INTRODUCED DURING THE CLASS. COMMUNICATION SKILLS THE STUDENT MUST BE ABLE TO COMMUNICATE, IN WRITTEN AND ORAL FORM, EFFECTIVELY AND RIGOROUSLY THE CONCEPTS LEARNED DURING THE CLASS. LEARNING SKILLS THE STUDENT NEEDS TO DEVELOP EFFECTIVE METHODS OF LEARNING OF THE FUNDAMENTAL ELEMENTS OF THE CLASS.

	Teaching Methods
	LESSONS (4 CFU) AND EXERCISES (2 CFU), EVEN WITH THE ADOPTION, DURING EXERCISES, OF INTERACTIVE METHODS THAT PROVIDE INFORMATION ON THE DEGREE OF UNDERSTANDING ACHIEVED BY STUDENTS. The class attendance is mandatory. The minimum percentage of presences is 70%.

	Verification of learning
	THE EVALUATION OF CLASS AIMS ACHIEVEMENT IS DONE at the end of the class BY MEANS OF WRITTEN AND ORAL EXAMINATION. THE WRITTEN TEST TIME DURATION CAN VARY BETWWEEN 3 AND 3 HOURS, ACCORDING TO THE TYPOLOGY OF PROBLEMS. THE WRITTEN TEST OF MECHANICS INCLUDES ONE OR TWO PROBLEMS (ACCORDING TO THE DIFFICULTY) OF KINEMATICS, DYNAMICS, STATICS. IN ADDITION, THE TEST INCLUDES A PROBLEM AND SOME QUESTIONS OF ACOUSTICS. THE CRITERIA ARE FOCUSED ON THE ABILITY OF THE STUDENT TO SOLVE PROBLEMS AND TO DESCRIBE PHYSICAL PHENOMENA RELATED TO CLASSICAL PHYSICS. IN THE WRITTEN EXAM, THE STUDENT MUST SOLVE PROBLEMS RELATED TO THE APPLICATION OF FUNDAMENTAL CONCEPTS, AND VECTOR AND INFINITESIMAL CALCULUS, TO CASE STUDIES OF ELEMENTARY PHYSICAL PHENOMENA. THE ORAL EXAM FOCUSES ON THE CHECK OF THE SUCCESSFUL LEARNING OF THEORETICAL AND APPLICATIVE ELEMENTS PRESENTED DURING THE CLASS, JUDGING IN PARTICULAR THE CONTENTS, THE ACCURACY OF THE ORAL PRESENTATION, THE VERBAL AND MATHEMATICAL EXPOSITION, THE ABILITY OF CORRELATING DIFFERENT TOPICS OF THE PROGRAM. THE RESULTS OF BOTH THE EXAMS ARE GIVEN IN POINTS, WITH A MAXIMUM OF 30. THE FINAL RESULT IS AGAIN GIVEN IN POINTS WITH A MAXIMUM OF 30 AND INCLUDES THE RESULTS OF BOTH WRITTEN AND ORAL EXAM. The result “cum laude” is obtained considering: -Clarity of exposition in terms of proper scientific language, -Ability to correlate different topics of the class, and, if possible, topics included in other disciplines, -Independence of judgement.
