Objectives of the course
This course gives the students basic knowledge to understand some physical aspects, to be integrated with Experimental physics II,
focusing on engineering application of physics. With lab experiences, this course teaches how to plan experiments, evaluate physical
quantities, in order to represent and use them in engineering works.
Expected skills
The student will be enabled to think in a scientific way and to apply abstract engineering mathematical concepts, focusing on points and
systems mechanics and thermodynamics.
Prerequisites
A good knowledge of basic physic studied at the high school and of Mathematical analysis I topics is required.
Syllabus
Credit 1: basics of experimental data treatment and groundwork for the execution of simple experiences.

- Concept of physical quantity and physical law.

- Basic and derivative quantities; unit of measurement systems.

- - Measures, uncertainties A and B.

- - Uncertainty in a measurement.

- - Evaluation of standard uncertainty A and B.

- - Propagation of uncertainty; expanded uncertainty.


Credit 2 Point mechanics.

- Point's kinematics. Speed and acceleration. Circular motion. Compound motion.

- - Point's force and dynamics. Different forces: weight force, rope tension, reaction force.

- Sliding friction force. Viscous friction force.

- Time-dependent forces, impulse and quantity of motion theorems.

- Positional forces. Work. Kinetik energy theorem.

- Conservative forces and potential energy.

- Mechanical conservation energy.

- Elastic forces and periodic motions.

- Binding points, reactive forces.

- Statics of a point. Stable, unstable and indifferent equilibrium.


Credit 3 Mechanics of points systems, of rigid systems and of deformable bodies.

- Points systems. Free degrees. External and internal forces.

- Mass center and its motion.

- Extention of quantity of motion theorems, of the kinetik energy.

- Central elastic and inelastic collisions.

- Introduction to a rigid body dynamic. Traslational motion. Equilibrium of a rigid body.

- Elastic phaenomena, elasticity law. Uniform compression and creep. Stretch. Torsion. Elastic anomalies.


Credit 4 Thermology and thermodynamics.

- Definition and measurement of temeperature. Perfect gas.

- I principle and perfect gas inner energy. Adiabatic transformations.

- II principle. Thermic machines. Kelvin-Pianck's and Clausius' postulates. Carnot's theoreme. Entropy.
Laboratories and/or exercises
Practicals are carried out in lecture halls with examples on studied topics. During the practicals are also discussed problems on a written
report of lab activites.


A first group of lab experiences concerns physical phaenomena connected to motor vehicle engineering.


- Measurement of sliding friction forces.

- Measurement of acceleration of gravity using a simple pendulum.

- Measurement of the momentum of inertia on a rotating platform.

- Measurement of a momentum of inertia with a torsional pendulum.


Professors are available to explain the students some topics of the program and of practicals, and to check, in an informal way, the
learning of the students. Students are divided into two groups.
