# PHYSICS

OVERVIEW

The Physics 1 course deals with the fundamental laws of mechanics and hydromechanics, essential for understanding any scientific and technological application the student will deal with during his training.

## AIMS AND CONTENT

LEARNING OUTCOMES

Understand basic physical fundamentals and the key vocabulary to describe them: kinematics, dynamics, work and energy, rotations, fluids. Develop skills in observation, interpretation, reasoning, synthesis, generalizing, predicting, and questioning as a way to learn new knowledge. Develop scientific problem solving skills, including organization of given information, identification and application of pertinent principles, quantitative solutions, interpreting results, and evaluating the validity of results. Apply conceptual understanding of the physics to general real-world situations, and recognize how and when physics methods and principles can help address problems in their future courses and then apply those methods and principles to solve new problems.

AIMS AND LEARNING OUTCOMES

Attendance and active participation in the proposed educational activities (lectures and exercises) and individual study will allow the student to:

- acquire the ability to describe and analyze the basic concepts concerning measurement of physical quantities

- understand and apply the fundamental laws of Kinematics

- understand and apply the fundamental laws of Dynamics to a variety of common situations

- understand, describe and apply the basic concepts of Kinetic and Potential Energy, Work and Power

- extend the fundamental laws of Kinetics and Dynamics to Rotation

- understand and apply the concepts of Equilibrium and Elasticity

- acquire the ability to describe and analyze the basic concepts regarding Fluid Satics and Dynamics

- understand Harmonic Motion and its applications

The student will be encouraged to understand the advantages and limitations connected to the use of schematics and models, employ scientific language and formalism correctly, recognize the applicability of schematizations and models in real-life situations, set and solve exercises and problems within the proposed contents and critically evaluate the results.

Teaching methods

Teaching is divided into lectures conducted by the teacher in which the theory will be exposed, which will be applied to different examples and through the resolution of exercises. In his personal work the student will have to acquire the knowledge and concepts underlying mechanics and hydromechanics and be able to solve exercises.

## EXAMS

Exam description

Written and oral exams.

Assessment methods

**Written exam**

Admission to the oral part of the exam only if the mark of the written exam is ≥ 16/30

Available only on official dates.

The student is allowed to repeat the complete test but the previous result will then be cancelled

As an alternative to the written examination at the end of the semester, two partial tests will be carried out in the middle and at the end of the semester: the grade for the first test must be ≥ 12/30 to allow access to the second partial test, otherwise the student will pass directly to take the full written examination at the end of the semester. To take the oral exam, the average score for the two tests must be ≥ 16/30

**Oral examination**

Those who take the oral examination having passed the two intermediate written tests will be able to propose to the committee the topic of the first oral question
