Ch 11: Properties of Rotational Motion

About This Chapter

Use this collection of lessons to study rotational kinematics and calculations involving the kinetic energy of rotation, work, power, and the moment of inertia. The illustrated video lessons and multiple-choice quizzes can give you plenty of practice with these rotational motion concepts.

Properties of Rotational Motion - Chapter Summary

Begin your review of rotational motion with lessons outlining the differences between linear and projectile motion as well as simple harmonic, circular, translational, and rotational motion. You'll also take a brief look at kinematics qualities before focusing on the dynamics of rotational inertia, torque, and rotational speed.

The second half of the chapter shows you how to determine an object's moment of inertia, calculate the kinetic energy of rotation, and plug variables into the translational and rotational equations for work. Wrap up your study of this topic with lessons explaining the difference between angular and linear momentum, and re-visit the applications of the law of conservation of angular momentum. You'll also review conditions for both translational and rotational equilibrium. Lessons in this chapter cover the following topics:

  • Types of motion
  • Big five kinematics equations
  • Rotational kinematics
  • Torque and rotational inertia
  • Kinetic energy of rotation
  • Work and power in rotational motion
  • Angular and linear momentum
  • Translational and rotational equilibrium

This chapter's lessons are self-paced and include video tags to help you quickly access the rotational motion concepts you need to review. There are also transcripts if you'd like to view this information while working on a rotational motion problem of your own, as well as self-checking lesson quizzes and a chapter test you can take as many times as you need.
