# Ch 2: Energy and Momentum

Watch video lessons to learn all about the various types of energy and the laws of thermodynamics. These lessons utilize engaging animations and graphics to help you easily retain key concepts associated with energy and momentum.

## Energy and Momentum - Chapter Summary and Learning Objectives

Work takes place when a force acts on something, causing a change or movement. Discover how energy influences you and the natural world surrounding you in this chapter. You can study the various types of energy, the work-energy theorem and the laws of thermodynamics through these video lessons with quizzes. By the time you work your way to the end of this chapter, you should be able to:

• Use the formula to calculate work
• Explain the relationship between kinetic energy and potential energy
• Discuss the laws of thermodynamics
• Describe the various forms of energy
