This article focuses on Friction and the role it plays in motion. Through models, friction is explained in a deeper way in the article. Sliding friction is focused on by showing models of cardboard boxes being dragged on a surface. The attraction of the molecules is discussed in detail, giving the reader a full understanding of what is happening during friction. As a topic of further inquiry, the writer briefly discusses the effects water has on friction. This could be helpful for a teacher who is looking to challenge his/her students. This article could be used as a resource for supplementary research in the classroom or outside the classroom. A teacher should utilize the resource to its fullest contents by bringing the models into the classroom for tactile learners.
