We often think of friction and air resistance as forces that we want to minimize because they can hinder the motion of an object. But they are not always undesirable, and in fact, can be an essential element in a machine or process. Identify one or two applications that depend on friction and air resistance. Explain how friction or air resistance works in those situations and what would happen if there were no friction or air resistance. Your initial post should be 75-150 words in length and is due on Sunday.
