Ch 6: Rotational Motion Principles: Help and Review

About This Chapter

The Rotational Motion Principles chapter of this NY Regents Exam - Physics: Help and Review course is the simplest way to master rotational motion principles. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of rotational motion.

Who's It For?

Anyone who needs help learning or mastering rotational motion material will benefit from the lessons in this chapter. There is no faster or easier way to learn rotational motion. Among those who would benefit are:

  • Students who have fallen behind in understanding rotational motion
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning physics (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about rotational motion
  • Students who struggle to understand their teachers
  • Students who attend schools without extra physics learning resources

How It Works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Rotational Motion Principles chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Rotational Motion Principles chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any rotational motion question. They're here to help!
