Training objectives
- The course aims to provide the basic elements of classical physics, the physical methods for the quantification of simple variables and the description of physical laws. The main goal is to provid students the ability to apply the principles of dynamics, the principles of hydrodynamics, the principles of thermodynamics to simple systems. The ability to discriminate between transversal and longitudinal waves, to apply the Ohm law to simple circuits, to discriminate between convergent and divergent lens.
The main knowledge obtained will be:
• Elements of the kinematics and dynamics.
• knowledge about the forces: gravity, elastic, electromagnetic;
• Knowledge of mechanic energy, thermal energy and elctromagnetic energy;
• Basic knowledge for studying systems fluidostatici and fluid.
• Basic knowledge to describe the state of thermodynamic systems;
• Basic knowledge to describe the behavior of electric circuits
• Basic knowledge to describe the behavior of electromagnetic waves and light.
• Measurement of a physical quantity and measurement uncertainty
The main skills (the ability to apply knowledge acquired) will be:
• analyze the behavior of simple physical systems;
• identify the types of energy present in simple physical systems Prerequisites
- Knowledge provided by secondary education and by the course of Mathematics with Elements of Statistics (first semester):
• Cartesian plane worksheet a coordinate sistems
• Knowledge of literal calculation, the fundamentals number sets and their properties
• Knowledge of the equations of first and second degree, systems of equations, disequations:
• Knowledge of the main trigonometric functions,
• Knowledge of the concept of limit, derivative and integral of a function. Course programme
