Constructing graphs in the process of solving problems is a common method in mathematics. It can make more abstract problems become concrete and intuitive, so as to solve problems more easily. Establish the awareness of using graphs to solve problems and improve the conscious use of graphs to solve problems. The ability to solve practical problems is very important. This paper uses physics as a background to discuss the application of structural graphics in solving problems.
