Problems solved by technology

At present, in the synthesis and decomposition experiments of force in high school physics, most of them use the form of general teaching aids and diagrams to show the parallelogram law of force. This kind of experimental teaching method cannot measure the force involved in specific objects and is not intuitive. , can not make students understand the essence of the experiment accurately and quickly; and the existing experimental devices are generally large in size, and experimental demonstrations are required in classroom teaching, or students operate in person, and the experimental devices are inconvenient to carry and carry, which affects the quality of experimental teaching

Abstract

The invention discloses a portable physical experiment device, and the device comprises a pedestal. The top surface of the pedestal is connected with a positioning device, and two sides of the positioning device are respectively connected with positioning blocks. The opposite side surfaces of the positioning blocks are each connected with one spring dynamometer, and each spring dynamometer comprises an upper hook connected with the corresponding positioning block. One end, far from the corresponding positioning block, of each hook is connected with a core column, and the exterior of each corecolumn is sleeved by a sleeve. A spring is disposed between the inner wall of each sleeve and the side wall of the corresponding core column. One end of each spring is connected with a side wall of anend, located outside the corresponding sleeve, of the corresponding core column, and the other end of each spring is connected with the bottom surface of the interior of the corresponding sleeve. Thebottom surface of the exterior of each sleeve is connected with a lower hook, and the top of each core column is connected with a scale. The top of a side wall of each sleeve is provided with a scalepointer. The device is reasonable in structure, is convenient to use, facilitates the improvement of the interest of students in exploring knowledge, improves the accuracy of the confirmatory experiment theory, and is convenient to store and carry.

Description

technical field [0001] The invention relates to the technical field of teaching experiment instruments, in particular to a portable physics experiment device. Background technique [0002] The decomposition of force means that the effect produced by the joint action of several forces can be replaced by one force. This force is called the resultant force of the aforementioned several forces. Find the component force process of a known force. That is, if several forces act together on an object to produce the same effect as a single force acting on an object, this force is called the resultant force of these forces, that is, the resultant force and component force are an equivalent substitution relationship . At present, in the synthesis and decomposition experiments of force in high school physics, most of them use the form of general teaching aids and diagrams to show the parallelogram law of force. This kind of experimental teaching method cannot measure the force involved...
