Abstract

The invention discloses a simple pendulum timing device, which includes a timer and a pendulum ball; the timer includes a housing, a display screen, a control module, a timing button, a switch, a photosensitive module, a timing module, and a power supply; the pendulum ball includes The pendulum ball and the laser light have a threading hole and a laser light groove on the pendulum ball, and the threading hole and the laser light groove are cylindrical and their axes coincide. The laser lamp includes a laser lamp housing, a battery, a key switch, a magnet sheet and a laser diode. Compared with the prior art, the beneficial effects of the present invention are: simple operation, practical and convenient, can reduce unnecessary human error in the experiment, improve the accuracy of timing, because the timer of the present invention is triggered by laser, it has strong stability , free from external light interference, and the distance between the pendulum ball and the timer is not limited.

Description

technical field [0001] The invention relates to the field of experimental instruments, in particular to a simple pendulum timing device. Background technique [0002] In physics teaching, there is a physics experiment that uses a simple pendulum to measure the acceleration of gravity. During the experiment, it is necessary to accurately measure the period of the simple pendulum. The general method is to manually record the time of N cycles, and then calculate the average value. ;In the process of timing, it is necessary to count the number of cycles, and then record the total time with a stopwatch. Sometimes the number of cycles is wrong due to human negligence, and there will be some errors in timing by pressing the stopwatch by hand, which will eventually affect the data. In the process of counting, the experimenters are also nervous and tired. Contents of the invention [0003] The technical problem to be solved by the invention is to get rid of the disadvantages of ma...
