单词 simple harmonic motion
释义

simple harmonic motion

Suppose that a particle is moving in a straight line so that its displacement x at time t is given by x = Asin(ωt+α), where A>0, ω, and α are constants. Then the particle is exhibiting simple harmonic motion, with amplitude A, period 2π/ω, and phase α. This equation gives the general solution of the differential equation inline

An example of simple harmonic motion is the motion of a particle suspended from a fixed support by a spring (see Hooke's law). Also, the motion of a simple pendulum performing oscillations of small amplitude is approximately simple harmonic motion.
