The description of the laboratory work «Experimental verification of the basic law of dynamics in the motion of a body in a viscous medium» is given, which is used in the educational laboratory "Mechanics" of the Department of Applied Physics of TvSTU. The theoretical part of the work contains an example of solving the differential equation of motion of a metal ball in a viscous medium under the action of gravity, the Archimedes force and the resistance force depending on the speed. The influence of the initial conditions on the nature of the body's motion is shown. As a method for checking the fulfillment of Newton's second law, a graphical method is used to confirm the direct proportionality of the distance traveled by the ball and the time of motion in the limiting case when the speed of the ball becomes almost constant.
