Abstract

The invention provides reaction time measuring equipment, and relates to the technical field of physics teaching instruments. The equipment comprises a measuring instrument bottom groove, a measuringinstrument cover plate is fixedly mounted on the front surface of the measuring instrument bottom groove; a motor placement box is fixedly mounted on the back surface of the measuring instrument bottom groove; a motor positioning plate is fixedly mounted in the motor placement box; a motor is fixedly mounted at the top of the motor positioning plate; the output end of the motor is sleeved with a rotary disc. A mark is arranged on the upper surface of the rotating disc, an in-place point mark is arranged at the bottom of the mark, a mark pointer is arranged on the front surface of the measuringinstrument bottom groove, a reading mark is arranged at the bottom of the mark pointer, an in-place observation hole is formed in the surface of the measuring instrument cover plate, and a positioning device is fixedly installed at the bottom of the in-place observation hole. The reaction time measuring equipment is simple in structure, clear in principle, convenient to operate, low in cost and high in practicability.

Description

technical field [0001] The invention relates to the technical field of physics teaching instruments, in particular to a reaction time measuring device. Background technique [0002] In high school physics teaching, in order to increase the interaction between teachers and students during class, teachers usually use a ruler to measure the students’ physiological reaction time in the form of free fall, through the height of the fall, and then according to the formula t=√2h / g Calculate the time, which is the student's physiological reaction time. This kind of teacher-student interaction activity can not only deepen students' understanding of free fall motion and mastery of formulas, but also measure students' physiological reaction time, which can greatly improve students' learning interest. [0003] However, there are certain shortcomings in the use of this kind of interaction: after the reaction time is measured, the result cannot be obtained immediately, and the result can...
