More Information
Summary:The utility model provides a display instrument for studying the regulations of the straight-line motion and the snaking motion in physics instruction, comprising an experiment panel rack, an arced guiding rail which is arranged on the experiment panel rack, and an isochronous and spray point chronoscope which is arranged in the guiding rail. The isochronous and spray point chronoscope is a cylindrical roller, comprising a timing ejector which is composed of a syringe and a miniature motor, and an eccentric orifice rotary disk which is arranged on the rotating shaft of the miniature motor. The display instrument can exactly and automatically record the shift and the motion law of the object in continuous and equal time once.
