What does “Simple harmonic motion” actually mean in Oscillations & Waves, and why does it matter for NEET?
oscillation where the restoring force is proportional to and opposite the displacement, F = −kx.
In simple words: oscillation where the restoring force is proportional to and opposite the displacement, F = −kx. Getting Simple harmonic motion clear matters because NEET questions on Oscillations & Waves usually test this idea directly, not just a formula you memorised.
Key point
Simple harmonic motion
Common mistake
assuming every back-and-forth motion is SHM.
Memory tip
only a linear restoring force (∝ −x) gives true SHM.
