Abstract: The process of friction of a rotating solid is studied. A model experiment is performed in which friction in the system is changed using sails oriented at different angles with respect to the airflow. The speed range is determined at which various types of friction play an important role: dry, viscous and aerodynamic, and the main parameters of different types of friction (the moment of dry friction force, coefficient of viscous friction) and the laws of their change depending on the experimental conditions are calculated.

Keywords: resistance factor, viscous friction, experiment.
