Fundamentals of physics and applied physics- mod.1: physics
Code: G290U-
Teacher:  Marco Lombardi
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 6
Basic aims:  The course will provide a basic knowledge of physical processes, with particular focus on dynamics and fluid dynamics for their impact on food technology.
Acquired skills:  Knowledge of the principal physical quantities (in particular, those that are often used during the studies), their dimensions and units of measurement. The student must be able to understand and to resolve formally and numerically simple problems of physics, related to the technological practices and to 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,
short description of electromagnetism, optics.
Program:  PHYSICAL MEASURES

- The fundamental units of the International System,
prefixes, derived units
- Scalar and vectors, dot product, and cross product

CINEMATIC
- Motion in one dimension: position and displacement,
velocity, acceleration, uniformly accelerated motion, free
fall
- Motion in multiple dimensions: trajectory, uniformly
accelerated motion, uniform circular motion, angular
velocity and angular acceleration

DYNAMICS OF EXTENDED SYSTEMS
- Center of mass and calculating the center of mass
- II Newton's law for particle systems, momentum and law
of conservation associated
- Elastic collisions and inelastic in one dimension

ROTARY MOTION
- Moment of inertia: definition, calculation, the theorem of
parallel axes, kinetic energy of a body in rotation
- II Newton's law for rotating rigid bodies, angular
momentum, and the law of conservation associated, torsion

GRAVITATION
- Law of universal gravitation
- Central forces and conservation of angular momentum
- Kepler's laws
- Gravitational force inside and outside a spherical mass
distribution

FLUID MECHANICS
- Definition of density and pressure
- Stevin's Law, the principle of Pascal and Archimedes'
principle
- Bernoulli's equation
- Ideal and non-ideal fluids: viscosity, surface tension and
capillary action

OSCILLATIONS AND WAVES
- Harmonic motion in one dimension: equation of motion
solution, kinetic and potential energy
- Pendulum
- Waves: transverse and longitudinal waves, wavelength,
frequency, period, and wave speed
- Mechanical waves: wave function, speed and wave
equation, superposition principle, interference, standing
waves

ELECTROMAGNETISM
- Electric charge and Coulomb's law, electric field
- Electric current, resistance, Ohm's law
- Introduction to the magnetic field
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. Additionally,
students whose written exam rises doubts regarding its
grading can be requested to take the oral exam. In any
case, the final mark of the exam will take into account the
performance at the oral exam: as a result, in case of bad
performance, the exam will be considered insufficient.
Students are allowed to sit a single oral exam for each
successful written exam.


SELF-ASSESSMENT TEST
(see http://www.marcolombardi.org/teaching/STAL)


During the course students will be provided with
assessment tests: these have to be carried out by all
students. The results of these tests will not be used in any
way for the final evaluation; their purpose is only to allow
each student to check what they have learned and follow
the best lectures.
