Problems solved by technology

However, in the existing experimental teaching, the measurement process of speed is relatively complicated, and it is difficult for the experimental equipment to capture the instantaneous movement position of the moving object, and the timing quantity and timing accuracy are insufficient. The most important thing is that the measurement process is not intuitive, resulting in No matter from the observation of the phenomenon or the induction and summary of the data, it is very vague, and it is difficult to understand the abstract laws. In addition, the existing experimental equipment is inconvenient to operate, and it often takes a lot of time and energy to conduct experiments, which leads to the efficiency of the experiment. Not high, it is difficult to achieve the expected effect

Abstract

The invention provides a speed measuring system and a speed measuring method. A moving object passes through detection devices, light waves of light wave emitting devices are emitted or reflected to light wave receiving units of the detection devices, and indication units of the detection devices are luminous when the light wave receiving units receive the light waves, so that the position of the moving object passing through the detection devices at certain time is recorded in real time. The speed of the moving object is acquired with the speed measuring method adopting distance-fixed timing or time-fixed distance measurement. According to the speed measuring system and the speed measuring method of the embodiment of the invention, the indication units of the detection units are luminous when the moving object passes through the detection devices, so that the accuracy of measurement time and distance is improved, the test efficiency is high, a large quantity of experimental data can be obtained, the test is convenient and fast, and the test range is wide.

Description

technical field [0001] The invention relates to the field of speed measurement, in particular, it provides a speed measurement system and a speed measurement method. Background technique [0002] In physics laboratories or physics teaching, the speed or acceleration of objects is often measured in order to calculate the physical quantities related to the speed. In teaching activities, the teacher measures the time and distance through physical experiments, and calculates the speed or acceleration, which can give the trainee a more intuitive and real look and feel, and facilitate the trainee's thinking and physical exploration. However, in the existing experimental teaching, the measurement process of speed is relatively complicated, and it is difficult for the experimental equipment to capture the instantaneous movement position of the moving object, and the timing quantity and timing accuracy are insufficient. The most important thing is that the measurement process is not ...
