Course Objectives
The course aims to provide students with a solid foundation in Classical Physics through the study of the fundamental principles of mechanics, wave phenomena, fluid mechanics, and thermodynamics. Particular emphasis is placed on understanding physical models and applying them to the solution of engineering problems.
With reference to the Dublin Descriptors, at the end of the course the student will be able to:
Knowledge and understanding: acquire the fundamental concepts of the kinematics and dynamics of a point particle and systems, as well as of oscillations, waves, fluid mechanics, and thermodynamics.
Applying knowledge and understanding: apply physical models and fundamental laws to solve problems in mechanics, fluid dynamics, wave propagation, and thermodynamic processes.
Making judgments: select the most appropriate models and principles to describe physical phenomena and evaluate the validity of the approximations employed.
Communication skills: communicate concepts, models, and solutions of physical problems clearly and rigorously, using appropriate technical language.
Learning skills: develop autonomy in the study of physics and related scientific disciplines, laying the groundwork for further studies of a technical and engineering nature.
Course Prerequisites
knowledge of elementary mathematics (algebra, geometry, trigonometry, analytical geometry)
Teaching Methods
lectures and exercises
Assessment Methods
The examination consists of two tests, one written and one oral.
The written test, lasting two hours, is designed to ascertain the student's ability to apply the knowledge acquired during the course to solving simple problems in mechanics, thermodynamics, and wave phenomena in elastic media. Successful completion of the written test gives access to the oral test.
The oral test is designed to ascertain the level of knowledge and understanding of the course contents (mechanics, thermodynamics, and wave phenomena in elastic media) and to assess autonomy of judgement, learning ability, and communication skills. The oral examination consists of a discussion of the written examination and questions and/or exercises on the course content.
The final mark is determined based on the joint assessment of the written and oral examinations, according to the following criteria, in line with the AVA 3 descriptors:
30 - 30 with honours Excellent
The student:
- demonstrates comprehensive and detailed knowledge of the subject: knows the relevant content, uses correct terminology, identifies and explains the main concepts, and integrates personal insights into their summary;
- demonstrates an excellent understanding of the subject: clearly distinguishes between main and supporting ideas, knows how to frame key points, reinforces arguments with references to supplementary material or individual insights, develops interdisciplinary links;
- demonstrates well-established ability to apply knowledge and analyse results;
- presents the subject matter in a clear and structured manner: their discourse is organized, logical, mature, and concise.
28 - 29 Excellent
The student:
- demonstrates in-depth knowledge of the subject: knows the relevant content, uses correct terminology, identifies and explains most of the main concepts;
- demonstrates a solid understanding of the subject: frames most of the key points, although does not always distinguish well between the main topics and the less important ones, discusses the topics with references to supplementary material or individual insights;
- demonstrates excellent ability to apply knowledge and analyse results;
- presents the subject matter clearly and articulately: his/her discourse is organized, logical, mature, and concise, although it may contain some inaccuracies.
25 - 27 Good
The student:
- demonstrates extensive knowledge of the subject: knows, even if not fully explaining, the relevant content; uses terminology, but not always accurately; identifies key concepts, but fails to explain them fully or accurately.
- demonstrates an adequate understanding of the subject: distinguishes important key points but fails to frame them completely;
- shows good ability to apply knowledge;
- expresses themselves clearly but not always completely, with a schematic organisation and sometimes fragmented and repetitive thoughts
22 - 24 Fair
The student:
- demonstrates acceptable knowledge of the subject: knows most of the content but has gaps in their knowledge and shows some confusion about certain important, though not essential, concepts;
- demonstrates a basic understanding of the subject: does not always manage to frame all the topics or sometimes does so inaccurately;
- demonstrates reasonable ability to apply the fundamental concepts of the subject;
- presents correctly, but without a completely clear and coherent structure, including some irrelevant material in certain points of the development.
18 - 21 Sufficient
The student:
- demonstrates limited knowledge of the subject: knows the most relevant content but has numerous gaps in their knowledge, identifies most of the key concepts but is unable to explain them completely and accurately;
- demonstrates a basic understanding of the subject: has some difficulty distinguishing the key points and is not always able to frame them correctly due to incompleteness or inaccuracy;
- shows uncertainty in applying the fundamental concepts of the subject; expresses themselves in an unclear and confused manner, uses language in a disorganised way, with fragmented and repetitive thoughts, and does not always use terminology accurately.
Insufficient
The student:
- demonstrates poor and fragmented knowledge of the subject: does not know the essential content, showing extensive gaps, and does not identify key concepts;
- shows serious errors in understanding, does not answer numerous questions or solve numerous problems; makes errors in applying the fundamental concepts of the subject;
- does not achieve an acceptable level of articulation of thought related to the subject.
