+## 2. Relevance
+
+There are numerous reasons why this project is relevant, as well as a wide range of potential applications. The following will outline the primary reasons and applications:
+
+- It can be used in the educational process. For instance, it can be used to illustrate some principles of mechanics to students and to visualize some physics problems.
+  
+- It can be used to simulate some physical experiments. For instance, it can be used to simulate the one described in _G. A. Galperin's work_[^1]. 
+
+- It can be used as a foundation for future projects.[^2]

 This leads to the conclusion that the wall will not change its position, but the particle will change its velocity value to the opposite.
