简谐运动是一种基本的机械运动,它不同于我们学过的一般直线运动和曲线运动,而是物体(振子)在平衡位置附近沿直线或圆弧所做的往复运动,物体运动的这种往复性是由其受力特点决定的.简谐运动主要有以下五个特征:一、受力特征F=-kx,负号“-”表示回复力 F 的方向与位移x相反;k 是比例系数,不一定是弹簧的劲度系数.总
Harmonic motion is a basic mechanical motion. It is different from the general linear motion and curvilinear motion we have learned. It is the reciprocating motion of an object (vibrator) near a balanced position along a straight line or an arc, and the motion of an object This kind of reciprocity is determined by its force characteristics. Harmonic motion mainly has the following five characteristics: First, the force characteristics F = -kx, the minus sign “-” means that the direction of the restoring force F is opposite to the displacement x; k is the proportional coefficient, not necessarily the stiffness coefficient of the spring.
