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 ELECTROMAGNETISM, WHICH ARE RELEVANT TO CIVIL AND ENVIRONMENTAL ENGINEERING, WITH PARTICULAR REGARD TO SCIENTIFIC METHODOLOGY;
- WILL ACQUIRE THE PHYSICAL BASIS FOR THE STUDY OF HIGHER-LEVEL SUBJECTS.

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 CONVENIENT 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 TEACHING AND THE METHODS OF SOLVING THE PHYSICAL PROBLEMS SUBMITTED.

ABILITY TO LEARN:
THE STUDENT WILL BE ABLE TO
- APPLY THE DIFFERENT KNOWLEDGE ACQUIRED DURING TEACHING TO CONTEXTS EVEN APPARENTLY DIFFERENT FROM THE CANONICAL ONES;
- 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.

Teaching Methods
LESSONS (8 CFU) AND EXERCISES (4 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, ENERGY. THE WRITTEN TEST OF ELECTROMAGNETISM INCLUDES ONE OR TWO PROBLEMS (ACCORDING TO THE DIFFICULTY) OF ELECTROSTATICS, MAGNETISM, ELECTROMAGNETIC INDUCTION. 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.
