CEOE Physics: Rotational Motion, Collisions & Conservation - Chapter Summary
This collection of lessons explores the basic laws of motion, equilibrium, momentum conservation and more. Watch our video lessons to get up to speed on the following physics concepts:
- Circular and rotational motion
- Angular and linear momentum
- The five equations for uniformly-accelerated motion problems
Our physics instructors are some of the most knowledgeable around, and they've crafted these videos to help you ace the CEOE Physics test. Take the quiz at the conclusion of each lesson to see what you've retained and which topics might need some review. Watch these videos as many times as you'd like, and send questions to our physics teachers whenever they arise.
Objectives of the CEOE Physics: Rotational Motion, Collisions & Conservation Chapter
The CEOE Physics test is typically taken by educators at the secondary level seeking subject-area certification in physics. The test consists of 80 selected-response questions and one open-response problem. Questions on motion, force and energy make up one of five total sub-areas on the test, and this Study.com chapter can help you prepare for that specific sub-area. You'll be asked questions about uniform circular motion, torque, simple harmonic motion and more.
You'll have four hours to complete the entire CEOE Physics test. A minimum score of 240 is required in order to pass, and you should receive your score three to six weeks after taking the test. All CEOE tests are be offered in only a computer-based format. There are specific time windows for registering and taking the physics test, so make sure to check the CEOE website for details.
1. Uniform Circular Motion: Definition & Mathematics
After watching this lesson, you will be able to explain what uniform circular motion is, in terms of both acceleration and forces. You will also be able to use equations for centripetal force and acceleration to solve problems. A short quiz will follow.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
