Slope demonstration device for physics teaching

Abstract

The invention discloses a slope demonstration device for physics teaching, and the demonstration device comprises a bottom plate. One side of the top of the bottom plate is welded with four support columns, and the top of each support column is hinged to an installation plate. The other side of the top of the bottom plate is provided with a vertical fixed plate, and the fixed plate is in threadedconnection with two horizontal threaded rods. One end of each threaded rod is rotatingly connected with a sliding block, and a side wall of the top of the bottom plate is provided with two chutes. Thebottom of each sliding block is slidingly connected in the corresponding chute. The top of each sliding block is hinged to a connecting rod, and the top of the connecting rod is hinged to the other side of the bottom of the installation plate. One side of the top of the installation plate is connected with a recycling bin, and one side wall, close to the installation plate, of the recycling bin is provided with an opening. A side wall of the top of the opening is provided with a speed sensor. The demonstration device can achieve the adjustment of the angle of the installation plate, and can achieve the replacement of friction plates with different coefficients, so as to obtain the motion conditions of an object on the friction plates with different coefficients at different angles. The demonstration device is good in demonstration effect.

Description

technical field [0001] The invention relates to the technical field of physics teaching, in particular to an inclined plane demonstrator 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 interactions, the most general laws of motion, and the experimental methods and thinking methods used. In modern times, physics has become one of the most basic subjects in natural science. 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. In the process of physics teaching, the teacher needs to use boring descriptions when explaining the movement process of the slider. The students are difficult to understand, the teacher is very hard, an...

However, like many other natural science theories, these laws cannot be proved, and their correctness can only be tested through repeated experiments

In the process of physics teaching, the teacher needs to use boring descriptions when explaining the movement process of the slider. The students are difficult to understand, the teacher is very hard, and the work efficiency is low. At present, there is a lack of teaching aids on the market that can directly demonstrate the movement of the slider. , for this reason we propose an inclined plane demonstrator for physics teaching
