Questions where students often pick the tempting wrong answer — make sure you know the right one:
In simple harmonic motion, where is acceleration greatest?✗ It stays constant throughout the motion.✓ At maximum displacement; it is zero at the equilibrium position.
Does a simple pendulum's period depend on the mass of the bob?✗ Yes, a heavier bob gives a longer period.✓ No — for small swings it depends on length and g, not mass.
Where is the restoring force largest in SHM?✗ At the centre of the motion.✓ At maximum displacement; it is zero at equilibrium.
