Fundamentals of Physics
A.Y. 2020/2021
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.
Lesson period: Second semester

Lesson period
Second semester
The teaching will be delivered in hybrid mode. Lessons will be held both in the classroom (in person) and by videoconference using Microsoft Teams (or zoom platform) according to the scheduled time (synchronous).
The face-to-face lessons will be approximately 50%, also depending on the general situation; depending on the regional health conditions, the lessons given in the presence may also be to a different extent from what is expected.
Students who do not participate in face-to-face lessons will still be able to carry out the same online activity in order to develop the same skills acquired through the activities proposed in the classroom.
The lesson times and all the details of the activities will be published on the website (https://scienzealimentari.cdl.unimi.it/it) by the start of the lessons.
Any updates will also be communicated through direct notices to students (consult often the mail @ students.unimi.it).
Also often consult the ARIEL teaching site for specific notices. The methods and criteria for participating in face-to-face lessons, which require a reservation with the appropriate app, will be published in due time in the online course.

Prerequisites for admission
Students will have to master the normal mathematics concepts learned in lower and middle schools. As an example, students are expected to know how to calculate the area and circumference of a circle, the volume of a cylinder, a cone, or a sphere, simple geometry theorems (Pythagora's, sum of internal angles of a triangle), the use simple trigonometric functions, and transformations between units of measurement.
It is also essential to have a minimum level of familiarity with algebra and literal calculus. Additionally, students must have followed the Mathematics course (and if possible taken the relative exam).
