Original Khojo Papers practice question — not from a past board paper.
Simple harmonic motion is the motion of a body in which the acceleration is directly proportional to the displacement from a fixed point and is always directed towards that point. The oscillation of a mass on a spring and the small oscillation of a simple pendulum are examples.

The defining relation is a = −ω2x.
