In the present article, a mathematical model is developed to describe the motion of solid particles of micro- and nano-size in a gaseous medium. The model is represented by certain integro-differential equation with appropriate initial and boundary conditions. A probabilistic interpretation of the model is provided and its solvability is studied. We find that unique solution exists at certain sufficient condition. It is shown that the Fokker-Planck equation can be obtained from the integro-differential equation. Finally, a generalization to the 2D case is performed.

This research paper demonstrates the use of experimental problem based learning tasks which students of computer science and information technology study programs realized through a semester in physics study course. In this course students had to master how to use several sensors and how to connect them to Arduino and acquire proper measurements and save them in a memory card. Students admit that in most of the experiments using Arduino as a data logger gives advantages to more easily deal with experimentation. Students appreciate that this kind of mastering physics is more related to their specialty and future work. It becomes more significant to use measuring devices not only in laboratories but also in different environments where specific data acquisition systems are necessary. Therefore with this teaching method students realize the real life needs and conditions.
