Lesson Plan: Work and Energy Science

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate work with the formula work = force × distance and relate work done to transfer of energy.


Students will be able to

  • know that energy can be measured in joules,
  • know that energy of different categories can be transferred to and from work,
  • calculate work done using the following formula: work done = force × distance.


Students should already be familiar with

  • the fact that an energy transfer can be a decrease in an object’s energy of one category that is accompanied by an increase in another object’s energy of the same or a different category,
  • the fact that the total decrease in the energy categories in a transfer is equal to the total increase in energy categories in the transfer.


Students will not cover

  • rearrangement of 𝑊=𝐹𝑑,
  • the sign of work done (all work is treated as positive),
  • microstructures of objects that correspond to magnetic, chemical, elastic potential, or thermal energy,
  • the term system,
  • dissipation.
