The course is classified as one of the basic educational activities for the Bachelor Degree in Environmental Sciences. It is aimed first of all at acquiring the knowledge and the comprehension of the main physical phenomena related to the classical Mechanics and Thermodynamics, that are fundamental for the major part of the Degree, developing at the same time the capability of using the logical-deductive reasoning. A further aspect considered throughout the course is the relationship of the physical concepts with the environmental aspects and applications, in order to put the study within a general perspective of sustainability.

The instructional goals of the course are:
1) development of the capability to solve classical Mechanics and Thermodynamic problems, by applying their main laws;
2) favouring and stimulating the use of a correct logical-deductive reasoning in the resolution of problems and in general within the activities related to the learning;
3) development of the capability to present concepts and scientific reasoning in a correct and rigorous formal way, both orally and written;
4) development of the necessary familiarity with the basic concepts of the Error Theory, in order to acquire an appropriate experimental approach to the scientific investigation, included the proper use of the scientific instruments;
5) to acquire familiarity with data processing protocols, as well as with the writing of a scientific report using the appropriate language.
1. Knowledge and understanding
1.1. To know and understand the main physics laws concerning the cassical concepts of kynematics, dynamics, thermodynamics.
1.2. To know and understand the main characteristics of the process of acquisition and processing of the experimental data.

2. Capability of applying knowledge and comprehension
2.1. To use the learned laws and concepts in the resolution of theoretical or practical problems, with a logical and deductive approach.
2.2. To know how the learned concept may find application in the study of environmental systems.
2.3. To know how to collect experimental data, to process them and to realize a final written scientific report.

3. Capability of judgement
3.1. To evaluate the logical consistency of the results coming from the application of the learned physical laws.
3.2. To critically evaluate and recognize the presence of mistakes, by a correct evaluation of the used method and of the numerical results.

4. Communication skills
4.1. To communicate both the knowledge and the effects of its application using the proper scientific language.
4.2. To interact with the teacher and with the other students in a constructive way, also during the activity in laboratory.

5. Capability of learning
5.1. To take comprehensive and rigorous notes, even by the interaction with the other students.
5.2. To properly select the bibliographic references for the study, even by the interaction with the teacher, possibly also for topics or examples that are not easily found in a textbook.
Having achieved the learning outcomes of the fundamental course “Mathematics and Exercises”. In particular, the student is expected to be familiar with concepts and methods of the vectors algebra, the differential and integral calculus, and the trigonometry.
INTRODUCTION
Presentation of the course and its contextualization within the learning process. Standard Unit System. Frame of reference.

KYNEMATICS OF THE MASS POINT
Position, velocity, acceleration. Uniform and accelerated rectilinear motion. Circular motion. Motion in a plane. Radial and transverse velocity, tangential and centripetal acceleration. Angular velocity and acceleration.

DYNAMICS OF THE MASS POINT
Concepts of force and (inertial) mass. First Newton law. Second Newton law. Classification of the forces. Weight, restraining reactions. Third Newton law. Static, dynamic and viscous friction. Elastic forces in one dimension. Simple harmonic motion. Work of a force. Kinetic energy. Kinetic energy theorem. Power of a force. Potential energy. Conservative systems: mechanical energy and its conservation. Energy balances.

DYNAMICS OF THE SYSTEMS
Definition of mass center. Theorem of the motion of mass center. Conservation of momentum. Angular momentum. Torque. Dynamic equations. Rigid body. Moment of inertia. Translational and rotational motion. Static equilibrium of bodies, statics equations.

FLUID MECHANICS

Confidence levels. Weighted average. Least squares method. Linear regression. One laboratory experiment, to familiarize with some instrumentation and apply the learned Error Theory concepts.
Any General Phisics textbook at a university level containing classical Mechanics and Thermodynamics is in principle suitable. Possibly, the student will show the text to the teacher for approval. It is however suggested the text:
J. Walker, D. Halliday, R. Resnick, “Fondamenti di Fisica Vol. I – Meccanica Onde Termodinamica”,
The text is also available as a single Volume, including Electromagnetism and Modern Physics, useful to develop further Physics topics by oneself, depending on the studies chosen within the Environmental Sciences.
Given the general character of the basic concepts of Error Theory, any university text containing them is acceptable. The following text is however suggested:
J.R. Taylor, “Introduzione all'analisi degli errori. Lo studio delle incertezze nelle misure fisiche”, Zanichelli, Bologna 1999.
As an integration, is also suggested the following text, freely downloadable from the website http://wwwcdf.pd.infn.it/labo/INDEX.html :
M. Loreti, “Teoria degli Errori e Fondamenti di Statistica”, Decibel-Zanichelli, Bologna 1998.
The method used to assess the acquired knowledge and skills consists of a written exam, along with the delivery of a short scientific report on the laboratory lessons. The final grade will be that of the written exam. The laboratory report is anyhow mandatory to validate the grade, and must be delivered at last on the day of written exam.
The written exam consists of a series of exercises, to be numerically solved justifying the used methods. The student has to demonstrate both to have acquired the concepts provided during the class and to be able to apply them coherently in the problems resolution. Depending on the semester structure, the written exam might be replaced by two intermediate written tests, one at about the middle and the other at the end of the course. The duration of the written exam is 2 hours (1 hour each in the case of the two intermediate tests). During a written exam, it is allowed only the use of a scientific calculator and the consultation of a formulary, directly provided by the teacher. The use of notes, textbooks and electronic devices is prohibited.
The exam is passed with a minimun acceptable grade of 18/30 and a highest achievable grade of 30/30 (possibly cum laude).
The laboratory report will present the activity (performed or followed) in the laboratory, and must contain the description of the experimental apparatuses, of the adopted strategies, of the masurements protocols, of the data processing, as well as the final results, including the uncertainty evaluation.
The teaching activity is organized as follows:
a) lecture-style presentations at the blackboard, inegrated by 1 or 2 powerpoint presentations about examples of physical application in the field of environmental sciences;
b) laboratory activity, to be organized depending on the numerosity of the students cohort, in which the students attend or participate in an experimental activity, to acquire familiarity with some scientific instruments and to apply the Error Theory learned concepts. The students are required to attend at least half of the lessons given in the laboratory.
Furthermore, in the moodle platform of the University will be present the possible didactic material presented as powerpoint projections in the classroom, as well as solved examples of previous exams exercises.
