EJSS Simple Harmonic Motion Acceleration Model
http://weelookang.blogspot.sg/2015/01/shm-chapter-10.html?view=flipcard

Acceleration

From v = vo cos ω t = x0 ω cos ω t
where xo is the maximum displacement
differentiating we get

a = d v d t = − ω2 ( x 0 s i n ω t ) = − ω2 x

Variation with time of acceleration
In terms of x:

Therefore, a = - xo ω2 sin ω t
= - ω2 (xo sin ω t)
which is the defining equation for S.H.M. !
a = - ω2 x

Variation with displacement of acceleration

since

a = – a0sin ω t

where ao is the maximum acceleration
where by a0 = ω2 (xo)
