Fundamentals of physics and applied physics- mod.1: physics
Code: G290QA_2
Teacher:  Paolo Arosio
Year: 
Term: 
CFU: 
CFU subdivision: Practices in classroom: 1
Basic aims:  The course is proposed to provide the fundamental knowledge of physics, required and correlated to other teachings foreseen by the Course of Degree.
Acquired skills:  Knowledge of the principal physical quantities (i.e. those that are often used during the Course of Degree), their dimensions and units of measurement. The student must be able to recognize and to resolve formally and/or numerically simple problems of physics, related to the technological practices and/or the research in the frame of food technology.
Course contents:  Physical measurements, kinematics, dynamics of a particle, dynamics of composite system, rotatory motion, gravitation, fluid mechanics, oscillations and waves, electromagnetism, optics.
Program:  PHYSICAL MEASURES

- Geometric Optics
Prerequisites:  All topics normally dealt in mathematics and physics
programs of high school are given as granted. Additionally:

CALCULUS
- Ability to perform simple algebraic operations in several variables
- Resolution of simple equations
- Derivatives and integrals for functions in one variable

GEOMETRY
- Theorems about triangles (Pythagora's, Euclid's)
- Trigonometry: definitions of trigonometric functions and main theorems
- Area and perimeter of the main plane figures
- Volumes and surfaces of the main solid
Preparatory instructions:  None. However, students are strongly encouraged to follow and take the exam "Elementi di Calcolo" before taking the exam of Physics (see prerequisites).
Learning materials:  Raymond A. Serway • John W. Jewett
Principi di Fisica, vol. 1 Casa Editrice Edises

or any other Physics book at a university level.

Other info:  WRITTEN TEST

The written exam consists of two parts: a short multiple choice test, followed by series of open-ended problems. The multiple test correction is provided immediately, and only students who have passed this test may remain and take the rest of the exam.

ORAL EXAM

At their discretion students can take an oral exam to
improve the mark obtained in the written.
