# Ch 7: Rotational Motion

Watch video lessons and learn about the various aspects of rotational motion. The quizzes that follow each of the lessons can help you gauge your comprehension of the materials.

This Rotational Motion chapter explores the ways in which things move in our physical world. A wheel is an example of an object that uses rotational motion. In this chapter, you'll take a look at kinematic properties, and explore the different types of momentum. You'll also perform calculations with rolling objects. Once you have completed these video lessons, you should be able to:

• Explain and use equations for rotational kinematics
• Define rotational inertia
• Understand the process of rolling motion
• Identify the differences between translational and rotational motion or translational and rotational equilibrium
