About This Chapter
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.
1. Angular Momentum vs. Linear Momentum
After watching this lesson, you will be able to explain the difference between angular and linear momentum and solve problems using angular momentum equations. A short quiz will follow.
2. Conservation of Angular Momentum
After watching this video you will be able to explain what is meant by conservation of angular momentum. You will also be able to use this concept along with the equation to solve problems. A short quiz will follow.
3. Differences Between Translational & Rotational Motion
After watching this lesson, you'll be able to explain the difference between translational and rotational motion, explain how translational quantities are replaced by rotational ones in physics and apply Newton's First Law to rotation. A short quiz follows.
4. Equilibrium: Translational & Rotational
Learn about the requirements for an object to be under translational or rotational equilibrium. Then work through a couple example problems that show how we can use translational and rotational equilibrium to find the forces acting on an object.
5. Five Kinematics Quantities & the Big 5 Equations
After watching this lesson, you will be able to list the five kinematics variables in rotational motion and use the five equations of constant acceleration to solve problems involving rotational motion. A short quiz will follow.
6. Kinetic Energy of Rotation
After watching this lesson, you will be able to explain what kinetic energy of rotation is, provide the equation to calculate it, and solve simple kinetic energy of rotation problems. A short quiz will follow.
7. Rolling Motion & the Moment of Inertia
After watching this lesson, you should be able to figure out the moment of inertia of an object as it rolls down a ramp and compare it to a theoretical value. A short quiz will follow.
8. Torque: Concept, Equation & Example
After watching this lesson, you will be able to explain what torque is conceptually and mathematically and use both the equation and Newton's First Law for rotation to solve problems involving torque. A short quiz will follow.
9. Rotational Inertia & Change of Speed
After watching this lesson, you will be able to explain what rotational inertia is, describe how it makes it harder to change the speed of rotation, and solve rotational inertia problems. A short quiz will follow.
10. Rotational Kinematics: Definition & Equations
After watching this lesson, you should be able to explain what kinematics is, give a rotational variable that corresponds to each linear kinematic variable, and solve problems using rotational kinematics equations. A short quiz will follow.
11. Work & Power in Rotational Motion
After watching this lesson, you will be able to explain what work and power are in the context of rotational motion and use equations to solve problems involving rotational work and power. A short quiz will follow.
