AP Physics 1: Work, Energy, and Power - Chapter Summary and Learning Objectives

Work, energy, and power are at the heart of physics. In this chapter, you'll learn the technical definitions of these categories and get some examples to help illustrate what they do. Our instructors have broken down this chapter into smaller lessons that each deal with one topic at a time. You'll see what the different types of energy mean and how forces are exerted on objects. You'll also learn the basic important formulas that describe the relationships between work, energy, and power. After completing this chapter, you should be able to:

• Define work, energy, and power
• Explain work and energy formulas
• Identify mechanical energy in a system
• Name different types of energy
