Learning outcomes
At the conclusion of the course, students will be acquainted with the basic concepts of physics, from terminology to units of measure and main principles. In addition, they will be able to attain a full understanding of the processes that will be dealt with in the successive teaching of scientific subjects belonging to the corresponding university courses, so much so that these notions will be thoroughly learnt.
Course contents
Introduction to Physics from Aristotle to Galilei and Newton's work (2h)
Measures: the international system of units of measure (4h)
Vectors: operations with vectors (4 h)
Rectilinear motion: position and displacement, average and instantaneous velocity, acceleration and uniformly accelerated motion - Two dimensional motion: position and displacement, average and instantaneous velocity, average and instantaneous acceleration, uniform circular motion (6 h)
Force and motion: Newton first, second and third law, attrition - Kinetic energy, work and power - potential energy and energy conservation - Center of mass, quantity of motion and impulse. Rotation: linear and angular variables, momentum - Rolling - Equilibrium and elasticity (10 h)
Fluids: Pascal's principle, Archimede's principle, ideal fluids, Bernoulli's equation (6 h)
Temperature, heat and first law of thermodynamics - Entropy and second law of thermodynamics. Transformations. Phase change. (8 h)
EXERCISES (20 h)

Teaching methods
The course is divided into two teaching units.
Theory: includes lectures in which the teacher draws preliminary
physical concepts.
Exercises: the teacher descibes the solutions of problems chosen to
help the students to use simple mathematical methods.
Assessment methods
The final exam ensures the acquisition of knowledge and skills expected through a single writte exam (1 h). The student will be invited to solve simple problems, on topics related to the three areas of kinematics and dynamics of rigid bodies, statics and dynamics of fluids including molecular phenomena in liquid and thermodynamics.
