物理中蕴含着许多优美和谐的对称性。深挖这些对称性,不仅赏心悦目,而且能简解物理题,尽享解题的对称美。一、竖直上抛运动中的对称美物体做竖直上抛运动,具有以“上行最高点”的对称性:上行与下行时间相等;末速度与初速度等值反向;上行与下行途经同一位置速度等值反向,位移相同。
Physics contains many beautiful and harmonious symmetry. Deeply digging for these symmetries, not only pleasing to the eye, but also to solve physical problems, to enjoy the symmetry of the problem-solving beauty. First, the vertical throwing motion of the symmetry of the United States to do the object on the vertical throwing movement, with “ascending point ” symmetry: the uplink and downlink time equal; the end speed and the initial speed of the opposite; uplink and Down the same location by the same speed reverse, the same displacement.
