Description

technical field [0001] The invention relates to a gravitational acceleration measuring device, in particular to a gravitational acceleration measuring device for physical mechanics, and belongs to the technical field of mechanical experiment device application. Background technique [0002] Gravitational acceleration is the acceleration of an object under the action of gravity. Also called free fall acceleration, expressed in g. The direction is straight down, and its size can be determined by a variety of methods. Usually refers to the acceleration of objects near the ground falling in the vacuum under the action of the earth's gravity, denoted as g. In order to facilitate the calculation, its approximate standard value is usually taken as the square of 980 cm / s or the square of 9.8 m / s. [0003] There are many problems in the measurement of gravitational acceleration in physical mechanics. The existing device for measuring gravitational acceleration has a relatively sim...

AI Technical Summary

Problems solved by technology

[0003] There are many problems in the process of measuring the acceleration of gravity in physics and mechanics. The structure of the existing device for measuring the acceleration of gravity is relatively simple, which is not convenient for accurate calculation of the falling height of the iron ball, which greatly reduces the accuracy of the experimental results. After the process, the object will collide with other objects, causing deformation or even damage to the object itself, affecting the quality of the object and making it inconvenient to use
