Ch 10: NYSTCE Physics: Rotational Motion, Collisions & Conservation

About This Chapter

Before you take the NYSTCE Physics CST watch these lesson videos to prepare for questions on rotational kinematics. Review what you know about the differences between translational and rotational motion, properties of rotational motion and equilibrium of motion.

NYSTCE Physics: Rotational Motion, Collisions & Conservation - Chapter Summary

The lesson videos of this chapter will help you prepare for questions on the New York State Teacher Certification Examinations (NYSTCE) Physics Content Specialty Test (CST) about the nature of rotational motions. In these videos our expert instructors will discuss topics of rotational motion and rotational kinematics so that you will be prepared for related questions on:

  • Difference between translational and rotational motion
  • Five kinematic qualities and equations
  • Rotational dynamics and torque
  • Rotational inertia and change of speed
  • Kinetic energy of rotational movement
  • Work and power in relation to rotation
  • Differences between angular and linear momentum

Remember to ask our instructors any questions you may have so that you will be able to master the material presented in the chapter before you take the NYSTCE Physics CST. Also complete the lesson worksheets and quizzes to reinforce your knowledge of the subjects you understand and discover subjects you don't. Once you've found the subjects you don't understand, improve your understanding of these topics by going back to the lesson videos with video tags linked to key points, or read over the lesson transcripts.

NYSTCE Physics: Rotational Motion, Collisions & Conservation Objectives

Future educators in the state of New York interested in teaching physics must take the NYSTCE Physics CST as a requirement for certification. This computer-based exam is composed of 90 selected-response questions and one constructed-response question and is administered in a four hour and 15 minute testing session. As you prepare for test day, use these lesson videos, worksheets and quizzes to refresh what you know about the study of rotational motion. Of the material covered by the exam 23% is on mechanics and thermodynamics, including systems involving rotational motion.
