Preconceived notions are thinking about a concept in only one way. Specially heat, gravity, and energy. Once a person knows how something works it is difficult to imagine it working a different way. Nonscientific beliefs are beliefs learned outside of scientific evidence. For example, one's beliefs about the history of world based on the bible. Conceptual misunderstandings are ideas about what one thinks they understand based on their personal experiences or what they may have heard. One does not fully grasp the concept and understand it. Vernacular misconceptions happen when one word has two completely different meanings, specially in regard to science and everyday life. Factual misconceptions are ideas or beliefs that are learned at a young age but are actually incorrect.
