Lesson Plan: Newton’s Second Law of Motion for Rotation in terms of Moment of Inertia and Angular Acceleration Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the torque on an object given its moment of inertia and its angular acceleration.

Objectives

Students will be able to

  • use 𝜏=𝐼𝛼 to find the torque on an object given its moment of inertia and its angular acceleration,
  • determine the moment of inertia of an object from a graph of its angular acceleration against the torque applied to it.

Prerequisites

Students should already be familiar with

  • angular momentum,
  • moment of inertia,
  • using 𝐿=𝐼𝜔 to calculate the angular momentum of an object,
  • Newton’s second law of motion for linear mechanics.

Exclusions

Students will not cover

  • torque in terms of a change in angular momentum in a given time,
  • the conservation of angular momentum,
  • reaction torques.
