Training objectives
- The objectives of the course are supplying solid knowledge
of classical physics, in particular of mechanics and thermodynamics, which are needed grounds of all sciences.
An introduction to special relativity will be provided at the end of the course. This allow to give a more complete picture of the laws of mechanics.
The main knowledge acquired will be:
-comprehension of the laws governing the motion of one point and of a system of points
-main features relatives to dynamic and static of rigid body
-introduction on propagation of mechanical waves in material mediums
- definition of perfect gas and its behaviour
-thermodynamic: first and second laws, entropy definition
The student will be supplied with the formal rigour and will show their abilities in properly formulating and addressing problems concerning the treated subjects. Prerequisites
- Robust knowledge of elementary mathematics and algebra, trigonometry and analytic geometry is advisable.
Basic knowledge of calculus is an asset. Course programme
- Main topics: Scientific method and vectors (Introduction). Kinematics and dynamics of the point mass (10/12 hours). Laws of forces (10 hours). Dynamics of systems of particles (8 hours). Particle collisions (2 hours). Oscillations and waves (4 hours). Thermodynamics (10/12 hours). Special relativity (4 hours).
Detailed topics: Measures and units of measure, vectors and laws of forces. Kinematics of the point mass and relative motion. Dynamics of the point mass and of systems of particles. Dynamics of rigid bodies. Work and energy. Gravitation and the gravitational field. Particle collisions. Oscillations and waves. Thermal equilibrium, head and temperature. Kinetic theory of gases. Ideal gases and real gases. First and second law of thermodynamics. Thermal machines and Carnot cycle. Reversibility and irreversibility in thermodynamics. Definition of Entropy. Special relativity: postulates. Relativistic kinematics. Lorentz transformations, velocity transformations, proper time. Relativistic dynamics. Momentum-energy relation and equivalence between matter and energy. Momentum-energy four vector.
Applications and exercises.
During the course will be suggested several topics to elaborate which are related to particular topic discussed and not. Didactic methods
- Frontal lectures on theory and its applications.
All the lectures will be done in presence and in streaming. The lectures will not recorded.
All the topics are presented during classes within the due amount of time, going through the mathematical and physical nitty-gritty of the principles, equations and theorems.
Students are continuously solicited to stop the teacher and ask questions. The same holds true for the classes devoted to exercise and problem solving.
All the material used by the teacher during classes (both theory and exercises) will be available on the classroom of the course after being discussed and presented. The aim is to urge the students to take their own notes (that should be compared and completed with the material furnished by the teacher) and to think about the problem presented.
A tutor is also available for helping and integrating the learning procedure Learning assessment procedures
- The learning assessment procedures is based on two tests:
1)Written test based on exercises to be solved (3 or 4 exercises). The exercises must be solved in 1.5/2 hours with the help of the their own, and it is strictly recommended to have a scientific calculator. The minimum mark to pass is 17/30 up to 30/30.
Passing the written test remains valid to access to the oral exam until the end of this academic year.
2)Oral exam on topic theory. The minimal mark to pass is 18/30. The typical duration is about 20-40 minutes.
The definitive mark is obtained as the weighted average between written test (weight =1 assigned) and oral exam (weight = 2 assigned), it must be not less than 18/30.
The successful of the examination attests the acquisition of the skills, reported in the above section "Training objectives". Reference texts
