Question

In SHM, acceleration is proportional to:

RankGuru · Accepted Answer

Simple Harmonic Motion (SHM) is defined by the governing equation:
$a = -\omega^2 x$
where:
- $a$: instantaneous acceleration
- $x$: displacement from the equilibrium position
- $\omega$: angular frequency 
The negative sign indicates that the acceleration (and thus the restoring force $F = ma$) is always directed towards the equilibrium position, which is **opposite** to the direction of displacement.
