Ch 8: AP Physics 1 Rotational Motion: Homeschool Curriculum

About This Chapter

The rotational motion unit of this AP Physics 1 Homeschool course is designed to help homeschooled students learn about rotational motion concepts. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our AP Physics 1 Homeschool course will benefit any student who is trying to learn about rotational motion concepts. There is no faster or easier way to learn about rotational motion. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn about rotational kinematics, momentum, rotational dynamics and equilibrium.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a physics curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and a rotational motion unit exam confirm understanding or identify any topics that require review.

Rotational Motion Unit Objectives:

  • Distinguish between rotational motion and translational motion.
  • Use rotational variables to create rotational kinematic equations.
  • Understand how the five kinematic qualities are related to the big five equations.
  • Learn about torque and rotational dynamics.
  • Discover how an object's rotational inertia affects its rotational speed.
  • Ascertain the kinetic energy of a rotating disk and falling mass.
  • Determine an object's moment of inertia based on rotational motion and conservation of energy principles.
  • Calculate the work, power and kinetic energy of objects in rotational motion using translational motion formulas.
  • Distinguish between linear momentum and angular momentum.
  • Solve problems using the law of conservation of angular momentum.
  • Understand the conditions for an object in rotational equilibrium and translational equilibrium.
