Lesson: The Scalar Product of Two Vectors Physics • First Year of Secondary School

In this lesson, we will learn how to calculate the scalar product of two vectors using both the components of the vectors and the magnitudes of the two vectors and the angle between them.

Lesson Plan

Students will be able to

use to find the scalar product of two vectors that are given in component form,
recognize that if two vectors are perpendicular to each other, their scalar product is zero,
recognize that the scalar product of two vectors has a maximum positive value when the two vectors are parallel and a maximum negative value when the two vectors are antiparallel,
use to find the scalar product of two vectors, where the length of each vector and the angle between the vectors are known.
