GENERAL OBJECTIVES
THE COURSE AIMS TO DEVELOP THE PHYSICAL SENSE AND THE ABILITY TO 'PROBLEM SOLVE', TO MAKE THE STUDENT CAPABLE OF TACKLING A PHYSICS PROBLEM WITH THE CORRECT METHODOLOGY AND WITH THE APPROPRIATE PHYSICAL AND MATHEMATICAL TOOLS, AND TO CONVEY THE FUNDAMENTAL CONCEPTS OF PHYSICS, WITH PARTICULAR REFERENCE TO WHAT OCCURS IN THE COURSE OF STUDY.

KNOWLEDGE AND UNDERSTANDING:
THE STUDENT WILL:
- WILL ACQUIRE KNOWLEDGE OF THE ELEMENTS OF CLASSICAL MECHANICS AND ACOUSTICS, WHICH ARE RELEVANT TO BUILDING ENGINEERING-ARCHITECTURE, WITH PARTICULAR REGARD TO SCIENTIFIC METHODOLOGIES;
- WILL ACQUIRE THE PHYSICAL FOUNDATIONS FOR THE STUDY OF HIGHER-LEVEL TEACHING.

ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING
THE STUDENT WILL BE ABLE TO:
- BE ABLE TO IDENTIFY CONCRETE PHYSICAL PHENOMENA TO WHICH THE ACQUIRED THEORETICAL KNOWLEDGE CAN BE APPLIED;
- BE ABLE TO MAKE CONNECTIONS BETWEEN THEORETICAL PHYSICAL MODELS AND APPLIED PROBLEMS OF ENGINEERING INTEREST.

AUTONOMY OF JUDGMENT:
THE STUDENT WILL BE ABLE TO
- DISCERN THE MOST APPROPRIATE METHODOLOGIES FOR ANALYSING THE PROBLEMS PRESENTED;
- EVALUATE THE PROCEDURES FOR SOLVING THE PROPOSED PROBLEMS USING THE MOST APPROPRIATE MATHEMATICAL TECHNIQUES.

COMMUNICATION SKILLS:
THE STUDENT WILL BE ABLE TO
- COMMUNICATE, IN WRITTEN AND ORAL FORM, IN A RIGOROUS AND EFFECTIVE MANNER THE CONCEPTS LEARNT DURING THE COURSE AND THE METHODS OF SOLVING THE PHYSICAL PROBLEMS PRESENTED.

ABILITY TO LEARN:
THE STUDENT WILL BE ABLE TO
- APPLY THE VARIOUS KNOWLEDGE ACQUIRED DURING TEACHING TO CONTEXTS EVEN APPARENTLY DIFFERENT FROM THE CANONICAL ONES AND
- DEEPEN THE TOPICS COVERED USING DIFFERENT AND COMPLEMENTARY APPROACHES.
Prerequisites
A) THERE ARE NO PROPAEDEUTIC COURSES.
B) THE CLASS REQUIRES KNOWLEDGE OF ELEMENTARY TOOLS OF ALGEBRA, GEOMETRY AND TRIGONOMETRY, KNOWLEDGE OF SIMPLE FUNCTIONS AND THEIR GRAPHS, AND FAMILIARITY WITH ELEMENTS OF VECTOR ALGEBRA.
Contents

Teaching Methods
LESSONS (ABOUT 36 HOURS) AND EXERCISES (ABOUT 24 HOURS). FRONTAL LECTURES WILL ENABLE THE STUDENT TO ACQUIRE THE FUNDAMENTAL ELEMENTS OF MECHANICS AND ACOUSTICS, AS WELL AS THE PHYSICAL BASIS FOR THE STUDY OF HIGHER LEVEL COURSES. THE EXERCISES WILL ENABLE THE STUDENT TO DEVELOP THE ABILITY TO APPLY THE ACQUIRED THEORETICAL KNOWLEDGE TO PROBLEMS OF ENGINEERING INTEREST, LEARNING TO IDENTIFY THE MOST APPROPRIATE METHODOLOGIES FOR ANALYZING THE PROBLEMS PRESENTED. THE EXERCISES WILL ALSO BE CARRIED OUT WITH THE ADOPTION OF INTERACTIVE METHODS THAT PROVIDE INFORMATION ON THE DEGREE OF UNDERSTANDING REACHED BY THE STUDENTS. AS PART OF THE EXERCISES, VISITS TO THE APPLIED PHYSICS LABORATORY FOR PRACTICAL ACTIVITIES ARE ALSO PLANNED.
THE CLASS ATTENDANCE IS MANDATORY AND WILL BE CERTIFIED USING THE TOOLS PROVIDED BY THE UNIVERSITY, IN PARTICULAR THE EASYBADGE APP. 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 MINIMUM GRADE IS ACHIEVED BY DEMONSTRATING KNOWLEDGE OF THE ELEMENTARY BASICS OF VECTOR CALCULUS, KINEMATICS AND DYNAMICS OF THE MATERIAL POINT, SYSTEMS OF MATERIAL POINTS AND RIGID BODIES, AND THE CONCEPT OF THE CENTER OF MASS.

THE MAXIMUM GRADE IS ATTAINED BY ANSWERING IN FULL DETAIL AND COMPREHENSIVELY ALL THE PROBLEMS AND QUESTIONS PROPOSED DURING THE WRITTEN TEST AND THE ORAL TEST, ON ALL THE TOPICS OF THE PROGRAM.

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.
