# A-level考前总结进阶数学重难点解析——简谐运动

A particle undergoes simple harmonic motionif its acceleration is directed towards a fixed point and is proportional tothe displacement of the particle from that point.

Displacement and velocity for simpleharmonic motion can be found

If given the displacement at a point, thevelocity can be found by:

v是线速度，是角速度，a是振幅，x是此时的位移。
