Fundamentals of Physics
A.Y. 2024/2025
Learning objectives
The course aims to provide students with the basic knowledge of physics, with particular regard to mechanics and fluid dynamics to provide them with the cultural prerequisites necessary to learn about the transformations to which food matrixes are subjected in food technology processes.
Expected learning outcomes
At the end of the course the students will know the main physical quantities, their dimensions and units of measurement. The student will be able to recognize and solve formally and numerically simple physics problems, related to the technological and research practices mainly used in food technology.

Prerequisites for admission
Students will have to master the typical mathematics concepts learned in primary and middle school. As an example, students are expected to know how to calculate the area and circumference of a circle, the volume of a cylinder, cone, or sphere, to know simple geometry theorems (Pythagorean theorem, sum of the internal angles of a triangle), to know and use basic trigonometric functions, and to be able to perform simple unit conversions.
It is also essential to have a minimum level of familiarity with algebra and literal calculus. Additionally, it is necessary to have attended (and possibly passed the related exam) the Mathematics course.
