Application of robotical sets in physical experiments

A robotic LEGO type set is used in two physical experiments. The first experiment is related to the phenomenon of sliding a permanent magnet over a non-magnetic conducting plate. High-precision automated measurement of the sliding time allowed confirming the constancy of the sliding speed and determining its magnitude. In the second experiment, the sliding of three steel balls of different diameters along a shoot was considered. The measurement of the sliding time showed that it is the same for all balls. With an accuracy of up to 5%, a factor of 0.4 is determined in the moment of the balls inertia.
