2. Know the units of physical quantities
3. Knowing the nature (scalar or vector) of physical quantities
4. Knowing these steps (vector calculus) between the physical quantities
5. Knowing the basic laws of physics addressed during the course
6. Know how to interpret and systematize the physical dynamics of a process and quantify the variables of interest
Skills (skills)
1. Knowing how to identify the physical processes involved in the processes under study
2. Knowing describe the physical processes identified by the models introduced
3. Know how to interpret the results obtained by physical modeling of the process
Behaviors (interpersonal skills)
1. Participate actively in the ongoing activities
2. Knowing how to identify the most appropriate techniques to solve problems - Prerequisites
- In order to understand the concepts presented during the course and to carry out the proposed exercises it is necessary that the student knows and is familiar with notions of algebra
(e.g. potencies, solutions of first and second degree equations, inequalities, systems of equations), angles and trigonometric functions, properties of triangles and Cartesian systems.
To tackle the problems of some of the arguments carried out, it will also be necessary to calculate the surface and volume of the most common flat and solid geometrical figures (e.g. triangle, circle, trapezium, cylinder, sphere). - Teaching methods
- The course is essentially divided into 4 topics (in addition to the introductory part): kinematics and dynamics of the material point, work and energy, fluid mechanics, thermodynamics and calorimetry. Each topic will be addressed through lectures during which the theoretical bases of each topic will be presented, accompanied by examples and exercises. There will be optional activities in classroom and at home that will increase, if carried out properly, the final vote.
- Learning verification modality
- The exam includes a written test and an optional oral exam.
Each test lasts 90 minutes and consists of multiple choice questions.
The oral exam is optional and will consist of a discussion of about 20 minutes aimed at verifying the level of knowledge of the theoretical topics, the ability to communicate them using an appropriate language. - Extended program
- Experimental method and physical quantities: experimental method, physical quantities and units of measurement, graphic representation of a law of physics.
