Simple Harmonic Motion (SHM)is a particular type of oscillation. It is useful because its time period stays the same even when its amplitude changes. 是最基本也是最简单的一种机械振动。当某物体进行简谐运动时,物体所受的力跟位移成正比,并且力总是指向平衡位置。 Lets think about a simple example ...
什么是简谐振动(Simple Harmonic Motion, SHM)?简谐振动是一种特殊的振荡运动,其特点是周期恒定,即不论振幅如何变化,完成一次完整振动所需的时间(周期,T)保持不变,单位是秒。频率(f),即单位时间内振动的次数,与周期存在以下关系:频率=1/周期(Hz)。位移是指振动质点离其平衡位置的距离,...
▍Simple Harmonic Motion 简谐运动。 Simple Harmonic Motion (SHM) is a particular type ofoscillation. It is useful because its time period stays the same even when its amplitude changes. 是最基本也是最简单的一种机械振动。当某物体进行简谐运动时,物体所受的力跟位移成正比,并且力总是指向平衡位置。
◆Definition of Simple Harmonic Motion: 简谐运动正式定义: A body is undergoing SHM when the acceleration on the body is proportional to its displacement, but acts in the opposite direction. 如果一个物体在外力作用下,其加速度与它的位移成正比例关系,并且其所受力的方向与位移的方向相反,那么它的运动...
