Course abstract

The aim of this course is to provide knowledge in physics, in accordance with the needs of further studies of agricultural engineering specialists. Course consists of lectures, practical works and laboratory works. During the lectures students are introduced to the theory and ways of describing physical laws. Practical works include practicing and understanding written exercises and calculating precise results. During laboratory classes students deal with hands-on exercises where they measure, process and analyze various data readings, as well as to plot graphs.

Learning outcomes and their assessment

After completing the course students will have:
1. knowledge of the regularities considered in the course of physics and a critical understanding of their applicability to describe real processes considered in their specialty. – The knowledge is assessed in laboratory works and tests.
2. skills to perform measurements of physical quantities and apply knowledge in calculations in the research of their field, to summarize and analytically describe the results, as well as to perform correct graphical representation of the results. – The skills are assessed in laboratory works.

3. competence to evaluate the results of measurements and calculations, solutions to problems, and to understand the impact of one's professional activity on the environment. – The competence is assessed in laboratory works and tests.

Requirements for awarding credit points

The requirement is – passing the exam.

In order to be allowed to take the exam, all tests must be written and the laboratory works must be performed and defended, and total 50% of the maximum possible points must be obtained.

Description of the organization and tasks of students’ independent work

Each student must process the experimental data obtained during the laboratory work (it is necessary to perform calculations in accordance to the assignment and, if required in the assignment, to plot a graph), and document the results in accordance to the requirements, as well as prepare for the defense of laboratory work by independently studying the study literature.

Criteria for Evaluating Learning Outcomes

Knowledge control:
1) Theory tests – 2;
2) Practical exercise tests – 2;
3) Laboratory works (development and defence) – 8.

Each part shall be evaluated by 0-10 points.
