Lesson Plan: Torque of a Force Physics • 9th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the formula 𝑇 = 𝐹𝑑 to calculate the torque of a force about a rotation axis and also to calculate the net torque.

Objectives

Students will be able to

use the following formula in all combinations: torque about a point due to a force = the force the perpendicular distance of the point of action of the force from the point,
recognize that the unit of torque is the newton-meter.

Prerequisites

Students should already be familiar with

center of mass,
the normal reaction force.

Exclusions

Students will not cover

objects that have forces acting on them at angles to the object other than right angles.
