Abstract

The invention discloses a friction force experiment demonstration device for a physical experiment. The device comprises a workbench, wherein a movable groove A, a movable groove B and a movable groove C are formed in the upper portion of the workbench, pressure sensors A are installed at one end of the movable groove A, one end of the movable groove B and one end of the movable groove C respectively, and an experimental device A, an experimental device B and an experimental device C are arranged on the movable groove A, the movable groove B and the movable groove C respectively. According tothe invention, the experiment demonstration device of the invention is provided with three groups of experiment equipment, experiments can be carried out according to the movable grooves with different roughness, friction force experiments can be carried out according to experiment devices with different heights, and the device is simple in structure, high in flexibility, capable of adjusting theheight of the workbench, shooting an experiment and transmitting a video to the display screen, convenient for students to observe, high in friction force experiment precision, simple to operate and capable of exploring the relationship between friction force and ground roughness and other factors.

Description

technical field [0001] The invention belongs to the field of teaching experiment appliances, in particular to a friction experiment demonstration device for physics experiments. Background technique [0002] In the physics class, physical experiments are an essential part of physics. Through physical experiments, the principles of physics can be intuitively displayed and students' understanding of the principles can be deepened. There are many physics experiments, especially those involving friction physics experiments. Because friction experiments are difficult, many physics courses do not carry out experimental operations. It is very difficult for students to learn friction. The existing friction experiments The flexibility of the device is poor, the function is single, it is not possible to set up multiple experimental groups for experiments, and the experimental process cannot be photographed and displayed on the monitor. It is not convenient for students to watch the ex...
