Ch 17: Describing Motion

About This Chapter

Improve your understanding of motion, including topics like scientific measurements and formulas for speed and velocity. If you are preparing for an exam or class discussion, these lessons and quizzes can quickly boost your confidence by testing your knowledge of the topics ahead of time.

Describing Motion - Chapter Summary

With this chapter on motion, you can review topics like speed, velocity, and distance. You can also gain a deeper understanding of classical relativity. By the end of the chapter, you should feel confident and prepared to:

  • Explain the elements of SI units
  • Discuss scientific measurements and calculate percentage error
  • Use formulas for calculating speed and velocity
  • Explain how distance relates to change in position
  • Graph position and speed versus time
  • Describe classical relatively

The clear and easy-to-follow teaching style used by our educators can help you quickly get up to speed on motion. A brief quiz is available for each lesson to test your knowledge. In addition, each lesson includes a full written transcript that you can print and use to study on the go.

Elements of the SI: Base & Derived Units

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.

Scientific Measurements: Accuracy, Precision & Percentage Error

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.

Speed and Velocity: Concepts and Formulas

3. Speed and Velocity: Concepts and Formulas

Did you know that an object's speed and velocity may not be the same? This lesson describes the concepts of speed and velocity relating to objects in motion. We'll look at a specific example to help learn how to calculate both speed and velocity.

Distance, Time & Average Speed: Practice Problems

4. Distance, Time & Average Speed: Practice Problems

After watching this video, you will be able to explain what distance is, explain how it relates to change in position, and calculate the average speed in various situations. A short quiz will follow.

Graphing Position & Speed vs Time: Practice Problems

5. Graphing Position & Speed vs Time: Practice Problems

After watching this video, you should be able to explain what position and speed are. You should also be able to plot position vs. time and speed vs. time graphs. A short quiz will follow.

Classical Relativity: Distance and Time Relation to the Observer

6. Classical Relativity: Distance and Time Relation to the Observer

It is not enough to ask how fast something is moving. We must ask how fast something is moving relative to something else. This lesson describes how classical relativity is used to explain how speed is relative to the state of motion of the object and the observer. Examples are used to help understand classical relativity.
