Lesson Plan: The Conservation of Mechanical Energy

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to explain the motion of a pendulum for which mechanical energy is conserved.

Objectives

Students will be able to

  • recognize that mechanical energy is conserved,
  • describe the structure of a pendulum,
  • describe the motion of a pendulum.

Prerequisites

Students should already be familiar with

  • the fact that doing work can cause a change in the potential energy and kinetic energy of an object,
  • the fact that the mechanical energy of an object is the sum of its kinetic energy and potential energy,
  • the formula 𝑇=𝐾+𝑃 (mechanical energy = kinetic energy + potential energy).

Exclusions

Students will not cover

  • dissipation of energy,
  • 𝐾=12𝑚𝑣,
  • 𝑃=𝑚𝑔,
  • 𝑊=𝐹𝑑.
