Eli Rodriguez 11/13/19 Honors English Mrs. Navarro “Friction” Friction is a force that resists motion. Motion is the action or process of moving or being moved. Friction occurs when there is an attraction between molecules. Friction occurs in most of our everyday life like with the soft rubber soles on shoes. Two cards in a deck sliding against each other. A person sliding down a slide is an example of sliding friction. In some cases, we want to prevent friction so it's easier to move. A good example of this is a ball or wheel. They roll to help reduce friction. Another way to reduce friction is with a lubricant like a grease or oil. Machines and engines use grease and oil to reduce friction and wear so they can last longer. Friction may not seem important to others, but without it, our world would come to a halt. The soles on shoes have grip so you don’t fall on the ground. Without friction, there would be limitations to what we can do on a daily basis. For example, if there was no friction we wouldn't be able to walk.
