## Chapter 4: Motion in Two and Three Dimensions

### Study Plan

The motion of volcanic bombs is an instance of projectile motion, and with the concepts developed in Chatper 4 we can address the following questions:

• Given the initial speed and direction of motion of the projectile, what are the horizontal and vertical components of the velocity and what are the horizontal and vertical motions? (Example 2, page 100)
• How high does the projectile rise vertically? (Example 4, page 105)

#### Organize

1. Prepare for lecture by reading the assigned sections from Chapter 4 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.
2. Take the checkup quiz and work the Checkup questions in your textbook to assess your understanding of basic concepts. Take note of any topics you need to review further.
3. Review the Examples from your textbook. These progress from simple to complex, and provide concrete illustrations of the concepts discussed.
4. Review the Problem Solving Techniques box on Projectile Motion from your textbook.

#### Learn

2. Access the Online Concept Tutorials given for this chapter. Tutorials use animation and interactive exercises to help develop your understanding of fundamental topics.
Projectile Motion
Sections: 4.1, 4.2, 4.4
3. Use the FlashCards to test your memory for new key terms and equations.
4. Work the end of chapter Problems and Review Problems assigned by your instructor. If your instructor has assigned SmartWork online homework, login from the right navigation pane.
