# Ch 7: AP Physics C: Work, Energy, & Power

Watch physics video lessons and learn about the relationship between work, energy, and power, plus more. These lessons are just a portion of our AP Physics course.

## AP Physics C: Work, Energy, and Power - Chapter Summary and Learning Objectives

If physics is about moving objects, then work, or an applied force that creates movement, is at the heart of this science. In this chapter, you'll learn the formal definitions of work, energy, and power as well as how the three are related. You'll look at experiments and situations that will help you understand the concepts in each video. You'll see the different types of energy in action and how energy works within a system. This chapter is designed to teach you:

• The definitions of work, energy, and power
• The equations relating work, energy, and power
• How to make calculations about work
• The different types of energy
