Reviewing Measurement: Introduction

In a quest to understand the world around us, scientists try to work out relationships among physical quantities that can be measured. In order to fully understand those relationships, you must have a firm understanding of units, orders of magnitude, the unit system used in AP Physics 1, and how we use those measurements. In this section, you will be exploring these concepts more fully so that you can be successful in AP Physics 1.
