物体的动态平衡是指物体在运动中的平衡.它是通过控制某一物理量,使物体的状态发生缓慢变化,在此过程中,物体始终处于一系列的动态平衡状态.这类问题具有一定的综合性和求解的灵活性,可以充分考查学生分析问题、解决问题的能力.本文以实例对这类问题进行讨论.
The dynamic balance of an object refers to the balance of the object in motion. It controls the physical quantity to cause the object’s condition to change slowly. In this process, the object is always in a series of dynamic equilibrium states. Such problems have a certain degree of The comprehensiveness and flexibility of the solution can fully examine the students’ ability to analyze problems and solve problems. This article discusses such problems with examples.
