Learning objectives


The couse aims to provide the student with the fundamental concepts of mechanics and thermodynamics, through examples and exercises. During the course, the student will learn how to discuss and solve simple problems, to understand and describe physical phenomena as well as the physical properties of matter that he can experience in everyday life.The course will provide the following skills:
- knowledge of the correct scientific terminology used in Mechanics and Thermodynamics.- knowledge of the fundamental laws that describe the physics of Mechanics and Thermodynamics;- solving simple problems, analytically and numerically;- developing a rigorous scientific language, to transmit accurately the knowledge acquired and to describe physics phenomena;- critical assessment of his advancement in the study of physics;- critical discussion of the results obtained while solving physics problems, in particular focusing on errors and non-physical results; - to formulate simple observation and adequate predictions in real-life situations involving the physics of this course.

Prerequisites


Basic Mathematical analysisTrigonometry, equations and systems of equations, exponential, logarithm, real variable functions, limits, derivatives and integrals.The first lessons of the couse will be focused on the bases of vectorial calculus.

Teaching methods


Frontal lessons, where the main concepts will be discussed with examples and simple problems. Each part of the course in completed by a number of hours dedicated to exercises.

For some highlights and problems, short online video lessons will be available for “flipped classroom” activities.

Assessment methods and criteria

Two written partial tests of which the first one during the year (duration 1h20 ') or written test on the whole program alternatively (duration 2h).
Written tests will present both numerical or literal exercises and theoretical questions.

If 18/30 or above is achieved in both partial tests, the exam is passed. An oral test can be taken to improve the vote.

If the average of the partial tests is above 18/30 but one of the partials was not sufficient, the oral test is mandatory.

The total exams are passed with marks above or equal to 18/30. An oral test can be taken to improve the results.
