摘要
通过具体例题分析差异化的斜面机械效率,进而对有用功、总功进行明确界定,有助于加深学生对斜面机械效率的理解和正确求解。
In this paper,we discuss the mechanical effi ciency of the inclined plane by analyzing the specifi c examples,and then defi ne the work and the total work clearly,which can help the students to further understand and exactly solve the mechanical effi ciency of the inclined plane.
