Lesson Plan: Elastic Potential Energy Physics • 9th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the elastic potential energy stored in springs that are not at their equilibrium length.


Students will be able to

  • use the following formula in all combinations: change in elastic potential energy of a spring = 12× spring constant × (change in length from equilibrium length).


Students should already be familiar with

  • Hooke’s law,
  • the formula work done = force × distance moved in direction of force.


Students will not cover

  • oscillations of springs.
