对称是重要的美学要素,客观世界普遍具有对称性。对对称的理解,艺术家、工程师、科学家会有很大的不同。高中物理知识中也蕴含着对称美,教师有意识地开展对称性教学,对于培养学生的科学思维方式是非常有意义的。用这种思维方法来处理问题可以开拓思路,使复杂问题简单化。高中物理习题教学中对称性的应用使得烦琐死板的问题有了灵性和活力。例1从离地面高度为h、与墙壁相距s处,正对墙水平抛出一弹性小球,小球与墙壁发生碰撞后,其 Symmetry is an important aesthetic element, and the objective world is generally symmetrical. The symmetry of understanding, artists, engineers, scientists will be very different. Symmetry beauty also exists in the physics knowledge of senior high school, and the teachers consciously carry out the symmetrical teaching is very significant for cultivating students’ scientific thinking mode. Using this way of thinking to deal with problems can open up new ideas and simplify complex issues. The application of symmetry in high school physics exercises makes the problems of cumbersomeness and flexibility spiritual and energetic. Example 1 from the height of the ground h, and the wall at a distance of s, is throwing a horizontal elastic wall of the ball, the ball and the wall after the collision, its
