描述物理现象的各物理量之间常存在着相互依赖、相互制约的关系,当其中某个物理量变化时,其他物理量也将按照物理规律发生变化,许多命题以此设计情景要求对这种变化进行分析、讨论,即物理动态问题.物理动态命题能够突出考查考生综合分析、严密推理、
There are often interdependencies and mutual restraints among the physical quantities that describe the physical phenomena. When one of the physical quantities changes, other physical quantities will also change according to the laws of physics. Many propositions use this design scenario to analyze this change , Discussion, that is, the physical dynamics of the problem.Physical dynamic proposition can highlight the test examinee comprehensive analysis, rigorous reasoning,
