摘要
Abstract
Through the graphic method,the formula of elastic potential energy of spring can be deduced based on the relationship between work and energy. It turns out that this formula changes as the zero point of potential energy changes. This can clarifies the students′ misconception about the magnitude and negative of elastic potential energy.关键词
