FIELD: physics.SUBSTANCE: group of inventions relates to physics visual aids. An electric motor is mounted on an object. A nut is placed on the screw shaft of said motor, the nut having contact with the body of the object which, during rotation of the shaft, enables the nut to move along the axis of the shaft and move a load placed on the nut, tied by a thread to the body of the object, to the support of the shaft. Upon meeting the support, the load is released from the nut downwards and through the tensioned thread kinetic energy of the fall of the load is converted to translational movement of the object.EFFECT: simulating movement of an object using the weight of a load.2 cl, 1 dwg |
