Question 9

Simple Harmonic Motion

If a freely suspended object is pulled to one side and released, it oscillates about the point of suspension because the

  1. A.acceleration is directly proportional to the displacement
  2. B.motion is directed away from the equilibrium point
  3. C.acceleration is directly proportional to the square of the displacement
  4. D.velocity is minimum at the equilibrium point.
Show the answer and explanation

Answer: A (acceleration is directly proportional to the displacement)

Explanation

The restoring force, and so the acceleration, is proportional to the displacement and directed back towards the equilibrium point. This is simple harmonic motion.
