In view of the importance of theorem of kinetic energy and theorem of momentum in the whole high school physics knowledge systems,firstly,the paper expounds the two theorems in detail from their conceptions.Secondly,we analyze the advantages between the two theorems with formula of kinematics just relying on two praxis.Finally,we emphasize the details which we need to caution when we use the two theorems to solve some questions.%鉴于动能定理和动量定理在整个高中物理知识体系中的重要性,本文首先从概念方面对二者进行详细阐述,然后以两道习题为例分析动能定理和动量定理相比运动学公式在解题方面的优势,最后给出二者应用于计算时需要注意的细节。
