About This Chapter
NYSTCE Physics: Rotational Motion, Collisions & Conservation - Chapter Summary
The lesson videos of this chapter will help you prepare for questions on the New York State Teacher Certification Examinations (NYSTCE) Physics Content Specialty Test (CST) about the nature of rotational motions. In these videos our expert instructors will discuss topics of rotational motion and rotational kinematics so that you will be prepared for related questions on:
- Difference between translational and rotational motion
- Five kinematic qualities and equations
- Rotational dynamics and torque
- Rotational inertia and change of speed
- Kinetic energy of rotational movement
- Work and power in relation to rotation
- Differences between angular and linear momentum
Remember to ask our instructors any questions you may have so that you will be able to master the material presented in the chapter before you take the NYSTCE Physics CST. Also complete the lesson worksheets and quizzes to reinforce your knowledge of the subjects you understand and discover subjects you don't. Once you've found the subjects you don't understand, improve your understanding of these topics by going back to the lesson videos with video tags linked to key points, or read over the lesson transcripts.
NYSTCE Physics: Rotational Motion, Collisions & Conservation Objectives
Future educators in the state of New York interested in teaching physics must take the NYSTCE Physics CST as a requirement for certification. This computer-based exam is composed of 90 selected-response questions and one constructed-response question and is administered in a four hour and 15 minute testing session. As you prepare for test day, use these lesson videos, worksheets and quizzes to refresh what you know about the study of rotational motion. Of the material covered by the exam 23% is on mechanics and thermodynamics, including systems involving rotational motion.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
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. 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.
9. 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.
10. 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.
11. 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.
