Vectors and Scalars

A marching band helps us explore the difference between vector and scalar quantities. We also dive into how to use the tip-to-tail method to resolve one- and two-dimensional vectors.

## Learning Objectives

-Introduce vectors and scalars and show examples.

-Note that vectors are represented with arrows and how we use coordinate axes to explain their heading.

-Illustrate magnitude and direction.

-Show how to add vectors using the tip-to-tail method.

## Vocabulary

magnitude - the amount or quantity.

Pythagorean Theorem - a theorem that states that the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

scalars - quantities that are described by magnitude alone (e.g. time, speed, mass, distance).

vectors - quantities that express magnitude and direction.

## Request Teacher Toolkit

The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study.  GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
