摘要:
大多数大学物理教材仅将动能定理简单地描述为“动能定理的形式不依赖于惯性参考系”,而没有给出严格的证明,这使得学生难以真正理解动能定理.针对这一问题,本文首先利用不同惯性参考系之间的速度变换方法证明了动量定理形式不依赖于参考系的选取,然后基于此证明并利用类似的方法严格证明了动能定理形式不依赖于参考系的选取.该结果不仅能够丰富大学物理的教学内容,有利于学生全面掌握动能定理,而且还有助于提高学生的创新思维.
Abstract:
Most university physics textbooks simply describe the kinetic energy theorem as “the form of the kinetic energy theorem does not depend on the inertial reference system”, and does not give a strict proof, which makes it difficult for students to truly understand the kinetic energy theorem. To address this issue, the paper firstly uses the velocity transformation method between different inertial reference systems to prove that the form of momentum theorem does not depend on the reference system. Then, based on this proof, the similar physical method is used to prove that the form of the kinetic energy theorem does not depend on the reference system. The results of this paper can not only enrich the teaching content of university physics and help students to fully grasp the kinetic energy theorem, but also improve students' ability of innovative thinking.
