| Summary: | The momentum is often used to analyse the dynamics of the motion of an experimental interaction between objects. Meanwhile, the interaction force tends to be challenging to observe and obtain. In this study, a simple video-assisted experiment was used to observe the interaction forces during the interaction of two magnetic objects. The interaction force between magnetic dipoles was obtained for each object position during the interaction experiment. The maximum force interaction was obtained when the two objects were at the minimum distance. The velocity of the object significantly influences the minimum distance between two objects during the interaction. In addition, we found that the law of linear momentum conservation holds for this interaction. Furthermore, the total kinetic energy before and after the interaction is identical, indicating an elastic interaction. This study is hopefully beneficial for students to reduce the limitations in understanding the interaction forces between objects. |
