The origin of these misconceptions could be as simple as observation of one's environment. You put a ball into motion, and it will come to rest. Instructors need to assume the responsibility of explaining friction, how things fit into our surroundings, painting the big picture, rationalizing what is seemingly irrational at first. The example of motion/friction is trivial; my point is that this idea should still apply to more complex concepts as much as possible. Maybe some coddling is necessary. An in depth psychological understanding of how students approach material, why they ask the questions they do, how they think, is just as necessary as extensive knowledge of physics. Understanding the audience is just as crucial as understanding the material. You must speak their language.
