Fundamentals of physics and applied physics- mod.1: physics
Code: G290QA_1
Teacher:  Marco Lombardi
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 5
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

- 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 MATERIAL POINT
- Newton's laws: the concept of force and mass, equations
of motion, action and reaction
- Inertial systems and non-inertial reference system
changes, notes on the apparent forces
- Examples of forces: weight force and constant g, elastic
force, centrifugal force, static and dynamic friction
- Work done by a force, conservative forces, potential and
kinetic energy, energy conservation, work of friction forces

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

- 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

- 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
- Electromagnetic waves

OPTICAL
- Electromagnetic waves
- Reflection and refraction, Huygens principle, interference
and diffraction
- 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.

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.
