Lesson Plan: Finding the Magnitude of a Vector Physics

Start Practising

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the magnitude of a vector given its horizontal and vertical components.

Objectives

Students will be able to

work out the magnitude of a vector given in component form using notation,
work out the magnitude of a vector shown on a grid.

Prerequisites

Students should already be familiar with

what vectors are,
notation,
the Pythagorean theorem.

Exclusions

Students will not cover

finding the components of a vector given its magnitude and argument,
vector addition or subtraction,
non-Euclidean geometries,
vectors in three dimensions.
