FIELD: experimental measuring technique.
SUBSTANCE: method can be used for measurement of speed of non-uniform motion of body having variable acceleration, at surface of fluid. Body is submerged into fluid at specific depth and Archimedes force is applied to the body. After that the body is accelerated in fluid and subsequent braking is performed in air till body stops completely. After that brake path is measured and current speed of motion of the body at surface of fluid is determined from length of brake path.
EFFECT: high precision of measurement.
