# PHYSICS I A - E

**Academic Year 2023/2024**- Teacher:

**LIVIO LAMIA**

## Expected Learning Outcomes

The student is required to achieve the following training objectives:

- physical quantities and dimensional analysis;
- vector calculation and applications;
- static and dynamic of the material point and of the rigid body;
- fluidostatic and fluid dynamics;
- thermodynamics

## Course Structure

The teaching method is generally the most congenial to the teaching of Physics 1. In particular, in addition to the classical lecture with the use of a standard blackboard, slides will be used to deepen some specific topics. In addition, multimedia files (video and / or audio) will be used to facilitate the understanding of some topics. In addition to this, teaching in cooperative learning is privileged, in which the classroom becomes a moment of development and apprehension of knowledge. Brainstorming will also be considered (mainly for the resolution of exercises submitted by the teacher) and flipped-classroom in which the students will be directly called into question to explain or illustrate exercises or theoretical topics. The verification method includes self-assessment tests during the entire second semester as well as exam tests with cross-section exercises on the course topics.

*Should the circumstances require online or blended teaching, appropriate modifications to what is hereby stated may be introduced, in order to achieve the main objectives of the course. Additionally, exams may take place online, depending on circumstances.*

*Information for students with disabilities and / or SLD: *To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on the didactic objectives and specific needs. It is also possible to contact the referent teacher CInAP (Center for Active and Participatory Integration - Services for Disabilities and / or SLD) of our Department, prof. A. Pagano.
