简谐运动是一种最简单、最基本的振动,它是分析各种振动的基础。想要彻底理解简谐运动并能够正确地理解和掌握它,一定要从最简单、最基本的概念着手。物体在跟位移大小成正比,并且总是指向平衡位置的回复力作用下所做的运动叫简谐运动。简谐运动规律的内容包括位移、回复力、加速度、速度、动量、动能、势能和机械能等各物理量的变化规律。 Harmonic motion is one of the simplest and most basic vibration, it is based on the analysis of various vibrations. If you want to thoroughly understand harmonic motion and be able to understand and master it correctly, you must start with the simplest and most basic concepts. Objects are proportional to the size of the displacement, and always point to the equilibrium position of the restoring force made by the movement called simple harmonic motion. The content of harmonic motion includes the laws of displacement, restoring force, acceleration, velocity, momentum, kinetic energy, potential energy and mechanical energy.
