在中学物理竞赛中 ,会涉及振动的动能、势能、圆频率以及振动方程的确定问题 ,以下简单谈谈这方面的有关内容 .任何一个物体 ,当受到大小与位移成正比且方向相反的力作用时 ,即 :Ｆ =-ｋ(ｘ -ｘ0 ) ,则物体做简谐振动 .如果物体质量为ｍ ,根据牛顿运动定律有 :ａ =-ｋｍ(ｘ -ｘ In the middle school physics competition, it will involve the determination of vibrational kinetic energy, potential energy, circular frequency, and vibration equations. The following is a brief discussion of this aspect. Any object that is subjected to a force that is proportional to and opposite in magnitude to displacement When, that is: F =-k(x -x0), the object performs simple harmonic vibration. If the mass of the object is m, according to Newton’s laws of motion: a = -km(x -x
