Physics Models, theories, laws, measures and uncertainties. Unit of measurement (International System). Description of motion: kinematics in one dimension, kinematics in two dimensions, carriers. Force and mass. Newton's laws. Circular motion. Law of gravitation. Work. Kinetic energy. Power. Conservative forces. Potential energy. Conservation of mechanical energy. Quantity of motion. Rotational motion e momenti. Vibrations and waves (harmonic motion, sound). Bodies in balance. Fluids (static, dynamic, viscosity, surface tension). Recalls of: temperature and kinetic theory, heat, principles of thermodynamics, thermal machines, entropy. Electric charge and electric field. Electric potential and electric power; capacity. Dielectrics. Electric currents. Circuits in direct current. Magnetism. Electromagnetic induction and Faraday laws. Magnetic properties of matter. Electromagnetic waves and their spectrum. Light: geometric optics. Wave nature of light (interference, diffraction, spectroscopy, polarization). Optical instruments. Quantum theory and Photoelectric effect. Models of the atom. De Broglie's length and hypothesis. Electronic and atomic force microscopy. Quantum Mechanics and quantum numbers.
Theory of Errors The experimental method, the experimental measure, the measuring instruments. Unit of measurement, unit of scale, dimensional analysis. Measurement errors: random and systematic errors. Evaluation of uncertainties in direct measurements. Significant figures. Discrepancy. Errors in repeated measurements: average as best estimate, standard deviation, standard deviation of the mean. Gaussian distribution. Propagation of errors: sum and differences, products and quotients. Calculation of errors for functions of a variable and for functions of several variables. Least squares method. Correlation coefficient. Graphs: linear scale, semilogarithmic scale, logarithmic scale.
