在高职物理定理中,动量定理和动能定理好似一对孪生兄弟。学生在理解时往往混淆两个定理的同异,在应用两个定理解答问题时也常常不知所措。针对这个问题笔者对于动量定理和动能定理的同异进行了粗略的探究。 In higher vocational physics theorem, momentum theorem and kinetic energy theorem are like twin brothers. Students tend to confuse the similarities and differences of the two theorems when they are understanding, and are often overwhelmed when applying the two theorems to solve the problem. In view of this problem, the author conducts a rough exploration of the similarities and differences between momentum theorem and kinetic energy theorem.
