About This Chapter
Measurement in Physics - Chapter Summary
Our instructors present the concept of SI units and the other units that make up this system. The factors that characterize accurate scientific measurement are introduced, along with uncertainty, unit conversion and dimensional analysis. You will also learn how scientific measurements can be obtained with common tools.
As you move on through the lessons, the concept of order of magnitude, how it's related to scientific notation and how it can be used for estimation purposes is revealed. This chapter will prepare you to:
- Understand what SI units are
- Calculate percentage error
- Take measurements with precision and accuracy using common tools
- Define order of magnitude and scientific notation
- Use the order of magnitude to estimate numerical results

1. Elements of the SI: Base & Derived Units
Discover what we mean by SI units. Then explore SI units further by learning about all the base units, and several examples of the derived units that make up the system.
2. Scientific Measurements: Accuracy, Precision & Percentage Error
Accuracy, precision, and percentage error all characterize scientific measurements and tell you something about how good the measurements are. In this lesson, learn what these terms mean and how to calculate percentage error.
3. Measurements & Uncertainty in Science
In this lesson, you will discover the importance of precision and accuracy in science while learning to make measurements. Also, you will understand how to perform calculations with measurements that conserve precision and limit uncertainty.
4. Unit Conversion and Dimensional Analysis
How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.
5. Scientific Measurement & Common Instruments
While you've probably measured something, you may not be familiar with some of the scientific instruments that help us measure length, volume, mass, and time. This lesson will explore some common and not so common scientific instruments to help you understand the world of scientific measurement.
6. Order of Magnitude: Definition & Examples
In this lesson, you will learn the definition of order of magnitude and how it is closely associated with scientific notation. You will also learn how to determine the quantity of orders of magnitude in numbers with interesting real-life examples. Following the lesson will be a brief quiz.
7. Order of Magnitude: Analysis & Problems
It is a wonderful skill to be able to estimate a numerical result without having to use a calculator or computer. In this lesson we show how to do this using the order of magnitude idea.
