Physics teaching experiment display system

Abstract

The invention relates to a physics teaching experiment display system, which comprises a base station and an experiment mechanism, and is characterized in that the base station is arranged on an existing working tabletop in a sliding fit mode, and the experiment mechanism is arranged at the upper end of the base station. According to the invention, the design concept of a multi-density measurementstructure is adopted for physics teaching experiment display; The whole arranged experimental mechanism has the function of measuring the triple density of solid, liquid and gas under the cooperationof other density measuring structures, so that the functions of the whole device are diversified, and the practicability and the display performance of the whole device are improved; the sponge stripand the sponge block can absorb and remove liquid carried by the elastic dynamometer and residual liquid on the surface of an object by means of the shape characteristics of the sponge strip and thesponge block, so that the probability that the density measurement result is influenced by additional factors is reduced to the maximum extent, and the accuracy of object or liquid density measurementis improved.

Description

technical field [0001] The invention relates to the field of physics experiment equipment, in particular to a physics teaching experiment display system. Background technique [0002] Physics is a subject that studies the most general laws of motion and the basic structure of matter. As a leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles. The research basis of scientific disciplines, the theoretical structure of physics fully uses mathematics as its own working language, and uses experiments as the only standard for testing the correctness of the theory. Experiments help students master the ideas, methods and skills of physical experiments, and enable students to develop Develop good experimental habits, complete experiments independently, and have a certain ability to independently observe physical phenomena and complete comprehensive design experiments independentl...

Problems solved by technology

[0003] 1. Common physical density measuring devices are mostly suitable for density measurement of solid, liquid or gas, so the overall utilization rate of the device is low and it is easy to appear that the demand for experimental equipment exceeds the supply. At the same time, solid and liquid can be measured. Among the devices for conversion density measurement, most of the devices use a single structure, and the liquid mixing and other phenomena that are prone to occur in a single structure can affect the measurement results;

[0004] 2. In the process of using the spring dynamometer to measure the density of solids and liquids, after the spring dynamometer has suspended objects for a long time for multiple cycles, the elasticity of its own spring is prone to decrease, resulting in the number of scales presented. There will be deviations, which will reduce the accuracy of the final density measurement. At the same time, more liquid remaining on the measurement structure and other structures will easily affect the measurement results.
