质点在做简谐运动时,运动过程中各物理量关于平衡位置对称,即在平衡位置的两侧对称的位置,加速度大小相等、速度大小相等。灵活运用其对称性,对我们解决实际问题有很大帮助。一、加速度的对称性的应用 When doing simple harmonic motion, each physical quantity in the process of movement is symmetrical about the equilibrium position, that is, symmetrical positions on both sides of the equilibrium position, the accelerations are equal and the velocities are equal. Flexibility in using its symmetry can be very helpful to our solution to practical problems. First, the application of the symmetry of acceleration
