Problems solved by technology
[0005] In the current DIS (digital information system, digital information system) experiment, it mainly includes three parts: the force probe, the collector and the computer. The data is sent to the computer through the data line for data analysis and display. In this way, it will be difficult to achieve the experimental conditions of simultaneously generating action force and reaction force
In addition, the connection of the DIS experimental device is complicated, the operation is very cumbersome, and due to the limitation of the laboratory environment, it is very inconvenient to rely on the computer to process the experimental results
Furthermore, when pushing and pulling two force probes, it is difficult to ensure that the directions of the two forces are on the same straight line, which obviously cannot accurately verify Newton's third law

Provided is a Newton's third law experimental apparatus. The Newton's third law experimental apparatus comprises a shell body, a cover plate, a first force probe, a second force probe, a connecting piece, a first pushing and pulling piece, a second pushing and pulling piece, a displaying device and a circuit board which is provided with a control circuit. The cover plate is detachably arranged on the shell body which is provided with a guide slot. The first force probe and the second force probe are slideably arranged inside the guide slot and arranged along a length direction of the guide slot. The first force probe is connected with the second force probe through the connecting piece, relatively far-away end faces of the first force probe and the second force probe are respectively provided with the first pushing and pulling piece and the second pushing and pulling piece. The circuit board and the displaying screen are arranged on the shell body. The Newton's third law experimental apparatus is convenient to use and the accuracy degree of the experimental results is high.
Description
[0001] technical field [0002] The invention relates to an experimenter for Newton's third law. [0003] Background technique [0004] The content of Newton's third law is mainly: the action force and reaction force between two objects are always equal in magnitude, opposite in direction, and on the same straight line. [0005] In the current DIS (digital information system, digital information system) experiment, it mainly includes three parts: the force probe, the collector and the computer. The data is sent to the computer through the data line for data analysis and display. In this way, it will be difficult to realize the experimental conditions of simultaneously generating action force and reaction force. In addition, the connection of the DIS experimental device is complicated, the operation is very cumbersome, and due to the limitation of the laboratory environment, it is very inconvenient to rely on the computer to process the experimental results. Furthermore, w...
