Lesson Plan: Kinetic Energy Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the kinetic energy of a moving particle of mass 𝑚 that moves with a velocity of magnitude 𝑣.

Objectives

Students will be able to

  • recall and state the definition of kinetic energy,
  • calculate the kinetic energy of an object given its mass and velocity,
  • calculate the mass or velocity of an object given its kinetic energy,
  • solve real-world problems involving kinetic energy,
  • calculate kinetic energy when the velocity is given in vector form,
  • use kinetic energy in combination with Newton’s second law to solve problems,
  • use kinetic energy in combination with the equations of motion to solve problems.

Prerequisites

Students should already be familiar with

  • vector notation and dot products,
  • Newton’s second law of motion,
  • the equations of motion.

Exclusions

Students will not cover

  • the work–energy principle.
