Generally in a SHM if acceleration is $a\;\sin wt$ then velocity is $\large\frac{a}{v}$$ \cos wt +v_0$ & position is $\large\frac{a}{w^2} $$(1- \sin wt)+V_0$.

In special case in which initial condition are zero then $x= A \sin wt;v= Aw \cos wt \; \& \;accn=-Aw^2 \sin wt$.

Only in such cases $x, v \;\&\; accn$ from a GP with $'w'$ as the ratio.

Thus depending on initial conditions the acceleration, position & velocity can be in any proportion with the initial conditions added.
