| Abstract: | The paper introduces the problems which should be paid attention to during the application of the momentum theorem from various examples.It points out the common mistakes during the application of the principles of work and energy without considering the momentum theorem.The paper also discusses a common experimental question in detail,which could lead to a comprehensive understanding of the momentum theorem. |
