Worked practice questions

What happens to the net restoring force on a spring mass at the equilibrium position?

  1. It is at maximum
  2. It is half maximum
  3. It vanishes entirely
  4. It doubles in size
Show answer and solution

Correct answer: C. It vanishes entirely

At the equilibrium position the displacement is zero, so the restoring force F = -kx is zero.

A mass on a spring moves toward equilibrium. What happens to the restoring force?

  1. It rises sharply
  2. It stays constant
  3. It turns infinite
  4. It decreases
Show answer and solution

Correct answer: D. It decreases

The force is proportional to displacement, which shrinks as the mass approaches equilibrium.

Why does an oscillating mass pass through x = 0 instead of stopping there?

  1. It has momentum there
  2. Force is maximum there
  3. Friction vanishes there
  4. Gravity pulls it on
Show answer and solution

Correct answer: A. It has momentum there

The force is zero at x = 0 but the mass carries momentum gained while accelerating, so it overshoots.
