GRANDO DANIELA (titolare) - 9 ECTS
Prerequisites
Elementary algebra, Euclidean and analytical geometry, trigonometry, derivatives and integrals. It is well recommended to take 'Fisica I' after ‘Geometry and Algebra’ and ‘Mathematical Analysis I’. Students with a curricular debt in Maths must first pass these two exams before attempting Fisica I.
Learning outcomes
This course provides grounding in classical physics, spanning from kinematics, dynamics, fluid dynamics and thermodynamics. The students are expected to achieve a better understanding of theories and concepts through practical classes. Beside developing problem solving ability, practical classes are of fundamental importance for mastering the acquired knowledge and discovering its links to everyday life.
Course contents
The course covers a range of topics in classical mechanics and thermodynamics. Topics are introduced by following a logic and analytical framework. Sessions of exercises are proposed for every topic.
