Ch 7: Rotational Motion in Physics: Tutoring Solution

About This Chapter

The Rotational Motion in Physics chapter of this High School Physics Tutoring Solution is a flexible and affordable path to learning about rotational motion in physics. These simple and fun video lessons are each about five minutes long and they teach the definitions, qualities and laws of rotational motion required in a typical high school physics course.

How it works:

  • Begin your assignment or other high school physics work.
  • Identify the rotational motion in physics concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our High School Physics Tutoring Solution will benefit any student who is trying to learn about rotational motion in physics and earn better grades. This resource can help students including those who:

  • Struggle with understanding rotational kinematics, kinetic energy of rotation, conservation of angular momentum or any other rotational motion in physics topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their rotational motion in physics unit
  • Cope with ADD or ADHD
  • Want to get ahead in high school physics
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about rotational motion in physics simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live physics tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about rotational motion in physics on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives
