You can watch these lessons on a computer, tablet or phone, and they require only a few minutes of your time. If you need to review key points in the lesson, video tags allow you to quickly find the passage you need without having to watch the entire video again.
Objectives of the OAE Physics: Rotational Motion, Collisions & Conservation Chapter
Teachers seeking Ohio certification in physics must pass the OAE Physics exam. This exam contains five content areas, called domains. Questions on the material this chapter covers are in the mechanics domain, the test's largest, which accounts for 28% of the total score.
The OAE Physics exam consists entirely of multiple-choice questions, and the exam is delivered on a computer. Taking the brief quizzes at the end of each of our video lessons allow you to get practice answering questions in this format, and also let you assess your knowledge and see where you might need additional study.
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.
