Ch 17: GACE Physics: Rotational Motion

About This Chapter

Completing the lessons and assessments of this chapter on rotational motion will enhance your skills and improve your knowledge of material tested on the GACE Physics test.

GACE Physics: Rotational Motion - Chapter Summary

As part of your preparations for the GACE Physics exam, these lessons can help you review topics that you may be tested on. In specific, this chapter will address the following:

  • Differences and similarities between translational and rotational motion
  • Applications of equations that determine the qualities of kinematics
  • Work, power and kinetic energy of rotational dynamics, rotational inertia, torque and speed change
  • Comparisons and contrasts of angular momentum versus linear momentum and their conservation
  • The parallel-axis theorem and the moment of inertia in rolling motion

Our lesson transcripts can be used as a guide to map out your studying! Each video is equipped with our tagging system so you can directly jump to major study points.

Objectives of the GACE Physics: Rotational Motion Chapter

The GACE Physics exam consists of two subtests. The material covered in this chapter is based on the Mechanics subarea, which constitutes 60% of the Test I portion. Both Test I and II will assess your knowledge and understanding of scientific concepts in order to determine your teaching ability and eligibility for middle or high school science courses in the state of Georgia. You may use our self-assessment quizzes provided at the end of each lesson to test your comprehension of the information covered on the exam and also give you insight to the types of questions you'll actually see on the day of the test.
