PHYSICS I F - O

The student is required to achieve the following learning objectives:

• Scientific method, measurement of a physical quantity, dimensional analysis; vector calculation;

• Kinematic, static and dynamic of the material point and of the rigid body;

• Hydrostatics and fluid dynamics;

• Fundamental concepts of thermodynamics.

The teaching method will be 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 will be used to facilitate the understanding of some topics. Teaching in cooperative learning and Brainstorming will also be considered to encourage the students’ curiosity. Flipped-classroom will be also applied to direct 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
