Problems solved by technology

When the experiment is in progress, the measurement of the whole experiment is completed by releasing the steel ball on the upper end of the glass tube. The experimental data often requires multiple sets of measurements. At this time, it is necessary to invert the round glass tube several times to return the steel ball. The operation is more complicated. It is cumbersome, and the position of the steel ball absorbed by the electromagnet after inversion is not fixed, and the steel ball will deviate from the measurement path when the re-measurement occurs, resulting in the failure of the experiment and the need to re-measure, which greatly wastes the time during the experiment

Description

technical field [0001] The invention relates to a physics experiment appliance, in particular to a multifunctional instrument device for a university physics experiment. Background technique [0002] The experiment of measuring the acceleration of gravity by the free fall method is currently one of the basic experiments of undergraduate physics subjects, and is an indispensable part of the current university physics experiments. It detects the magnitude of the free-fall gravitational acceleration g through the free-fall method of the object, and currently occupies an important position in the teaching and scientific research of university physics. [0003] At present, the existing gravitational acceleration measuring instrument usually uses a cylindrical glass tube and a photoelectric gate arranged outside the cylinder for experiments. During the experiment, the air in the cylindrical glass tube needs to be removed to make the measurement more accurate. When the experiment ...
