Syllabus
Prerequisites: Calculus I.
Target skills and knowledge: The law of mechanics for a particle and a system of particles. Fluids at rest and the basics of hydrodynamics. Foundations of thermodynamics.
Examination methods: The final examination is both written and oral. The written part requires the solution of exercises on topics discussed in the program and it can be replaced by partial assessments during the course. The oral exam covers topics addressed in the lectures.
Assessment criteria: The written examination aims at assessing the student's ability in solving autonomously simple exercises about mechanics and thermodynamics, employing the techniques learned during lectures. Goal of the oral examination is to verify the student's knowledge about topics of General Physics.
Course unit contents: 1) Introduction. What Is Physics? Measuring Things. The International System of Units: mass, length, time. Reference frames. Scalars and vectors, operations with vectors.
2) Kinematics. Motion of a particle along a straight line. Position and velocity. Average and instantaneous velocity. Uniform motion. Average and instantaneous acceleration. Motion with constant acceleration. Free-falling bodies. The harmonic oscillator. Motion in 2 and 3 dimensions. Position,velocity and acceleration. Circular motion. Projectile motion.
3) Dynamics of a particle. Force, inertial mass. Newton's three laws of motion. Momentum. Some particular forces: weight, normal force, friction, spring force, drag. Applying Newton's laws: inclined plane, particle falling in a liquid. Angular momentum and torque.
4) Work and energy. Work of a force. Kinetic energy and the work-kinetic energy theorem, Conservative forces and potential energy. Potential energy for the weight and spring force. Energy conservation. Power.
5) Relative motions. Reference frames. Relative velocity and relative acceleration. Inertial frames. The terrestrial reference frame.

First and second König's theorem. Systems of parallel forces, barycenter.
7) Dynamics of the rigid body. Rotation with a fixed axis: axial angular momentum, kinetic energy, work. Moment of inertia, determination of the moment of inertia for simple bodies. Steiner's theorem. Rolling without slipping. Conservation laws for rigid body motion. Static equilibrium.
8) Collisions. Collision between two point masses. Elastic and inelastic collisions. Conservation of momentum and energy. Collisions in 1 and 2 dimensions. Collisions between rigid bodies.
9) Gravitation. Central forces and their properties. Kepler's laws. Newton's law of gravitation. Gravitational potential energy. Escape velocity. The torsion balance, measuring the gravitational constant. Kepler's problem, trajectories and constants of the motion.

12) Ideal gas and real gas. Boyle’s, Gay-Lussac’s and Avogadro's Laws. Equation of state for an ideal gas. Gas thermometer. P-V diagrams and thermodynamic transformations of an ideal gas. Reversible and irreversible transformations. Thermodynamic cycles and work. Specific heat. Mayer’s relation. Free expansion and internal energy for an ideal gas.
