1势能最低原理的含义1.1势能最低原理的内容物体系由于其中各物体间有保守力(万有引力、弹力、电场力等)相互作用而具有的、由它们相对位置决定的能量叫位能,又称势能.势能的改变量取决于运动过程的始末位置,而与路径无关.取不同的零势能点,同一状态的势能也可以有不同的数值.不管取哪个位置为零势能点,只要物体(或物体系)具有势能,则当势能最低时,其状态是稳定的.也可以表述为当物体在保守力作用下运动时,最终一定是向势能低的位置运动即任何物体都有达到势能最低的趋势,这就是势能最低原理. 1 The meaning of the principle of the lowest potential of potential energy 1.1 The content principle of the principle of the lowest potential energy Due to the interaction between the objects in which there is a conservative force (gravitation, elasticity, electric field force, etc.), the energy called position energy determined by their relative positions is also called Potential energy changes in the amount of potential energy depends on the movement of the beginning and ending position, and has nothing to do with the path.While taking different zero potential energy point, the same state potential energy can have different values.Whether take the position of zero potential energy point, as long as the object (or When the potential energy is lowest, its state is stable. It can also be stated that when the object moves under the conservative force, it must eventually move toward the position with low potential energy, that is, any object has the lowest potential energy Trend, which is the principle of the lowest potential.
