A display system for physics teaching experiments

Abstract

The invention relates to a physics teaching experiment display system, which includes a base and an experimental mechanism. The base is installed on the existing work table through sliding fit, and the upper end of the base is provided with an experimental mechanism. The invention adopts multiple density measurement The design concept of the structure is used to demonstrate the physics teaching experiment. The experimental mechanism set up as a whole has the function of realizing the triple density measurement of solid, liquid and gas with the cooperation of other density measurement structures, so as to make the overall function of the device more diversified and improve the overall practicality of the device. The sponge strip and the sponge block according to the present invention can use their own shape characteristics to absorb the liquid carried by the elastic dynamometer and the liquid remaining on the surface of the object, so as to minimize the impact of additional factors on the density measurement. The result will affect the probability of impact, thereby improving the accuracy of the density measurement of objects or liquids.

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.
