简谐运动的对称美是指做简谐运动的质点处在关于平衡位置对称的两位置时,其位移、回复力、速度、加速度、动能、势能等物理量的大小相等,质点在关于平衡位置对称的两段位移内运动的时间长短相等。这部分知识结合弹簧模型可以考查牛顿运动定律、共点力的平衡以及能量等问题,综合性很强,解决起来难度较大。我们在处理过程中应仔细分析,结合对称性,找准几何 The symmetrical beauty of simple harmonic motion means that the mass of simple harmonic motion is in the two positions symmetrical about the equilibrium position. The physical quantities of the displacement, the restoring force, the velocity, the acceleration, the kinetic energy and the potential energy are equal in size. The particle is symmetrical about the equilibrium position The two segments of the movement within the same length of time. This part of the knowledge combined with the spring model can test Newton’s laws of motion, a total of the balance of power and energy problems, highly comprehensive and difficult to solve. We should carefully analyze the process, combined with symmetry, find out the geometry
