Mechanics experiment teaching aid for physics teaching

Abstract

The invention discloses a mechanics experiment teaching aid for physics teaching. The mechanics experiment teaching aid comprises a supporting vertical rod and a steel ball rolling groove. The supporting vertical rod is installed on a side face groove body of the steel ball rolling groove. A curved surface plate with scales is arranged on a side face rod body of the supporting vertical rod. A supporting transverse rod is arranged on the inner side face of a top rod body of the supporting vertical rod. The movement trajectory of an object under gravity can be demonstrated through the perpendicular falling of a second experiment rolling ball, the conversion of gravitational potential energy and kinetic energy under gravity can be demonstrated when a second experiment rolling ball hits the first experiment rolling ball, students can understand by comparing scale lines on the curved surface plate with scales with height scale lines on the inner side face of the steel ball rolling groove, and the students understand other friction resistance and the like when the initial slipping height of the second experiment rolling ball is different from the climbing ending height of the first experiment rolling ball, use is convenient, and the teaching of education workers and the understanding of students are facilitated.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, in particular to a mechanical experiment teaching aid for physics teaching. Background technique [0002] The full name of physics is physics. Physics is a natural science that studies the most basic structure of the material world, the most common interaction, the most general law of motion, and the experimental methods and thinking methods used. In modern times, physics has become one of the natural sciences. One of the most basic disciplines, the physical laws that have been verified by a large number of rigorous experiments are called physical laws. However, like many other natural science theories, these laws cannot be proved, and their correctness can only be tested through repeated experiments. . [0003] The existing technology has the following problems: Mechanics is an important content in physics teaching, and gravity is the primary knowledge point of mechanics. The lack of a gr...

Problems solved by technology

[0003] The existing technology has the following problems: Mechanics is an important content in physics teaching, and gravity is the primary knowledge point of mechanics. The lack of a gravity experiment teaching aid for physics teaching will not only increase the work difficulty of teaching workers, but also be unfavorable for students. understanding
