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.
