Why is the work done for a Hooke's-law spring 12Fe and not Fe?

  1. Fe is the momentum
  2. the spring only moves half the distance
  3. half the energy is lost as heat
  4. the force rises from zero to F, so the average force is F2
Answer

D) the force rises from zero to F, so the average force is F2

Work = average force × extension. SLO P-11-B-27 · Application
