OAE Physics: Work, Energy & Power - Chapter Summary
Use our videos to brush up on the work-energy theorem, conservative forces and the definition of power as you prepare to take the OAE Physics exam. These lessons and quizzes offer refresher information on the following topics that may show up in exam questions:
- Energy's significance in nature
- Characteristics of work
- Work performed by a variable force
- Kinetic and potential energy
- The work-energy theorem
- Effects of conservative forces
- Conservation of mechanical energy
- Definition of power
Our instructors have created enjoyable lessons, filled with examples that illustrate their points. The instructors are available to answer any questions you may have after completing these videos.
OAE Physics: Work, Energy & Power - Chapter Objectives
In Ohio, teachers must pass the OAE Physics exam in order to be certified to teach physics. The exam has five sections, called domains, and the material this chapter covers is in the domain on mechanics. This domain is the largest of the five, accounting for 28% of the exam's total score.
The OAE Physics test is administered by computer, and all its 150 questions are multiple-choice. The quizzes that accompany our lessons are multiple-choice as well. These quizzes allow you to practice answering these types of questions, and they also let you test your knowledge and determine where you need additional study before taking the exam.
1. What is Energy? - Definition and Significance in Nature
This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.
2. Work: Definition, Characteristics, and Examples
Pushing a wall all day may feel like work, but unless you get that wall moving you're not doing any work according to the rules of physics. In this video lesson, you'll learn how work is defined as well as how to calculate the amount of work done on an object.
3. Work Done by a Variable Force
Doing work on an object is a simple concept: we apply a certain force over a certain distance. But in real life, that force is rarely constant. Therefore, we need to understand variable forces and be able to calculate them accurately.
4. Kinetic Energy to Potential Energy: Relationship in Different Energy Types
This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.
5. Work-Energy Theorem: Definition and Application
Work and energy are closely related in physics. In this lesson, you'll learn what that relationship is as well as how we can apply it to various situations.
6. Conservative Forces: Examples & Effects
Learn how to tell if a force is conservative and what exactly is being conserved. Then look at a couple of specific examples of forces to see how they are conservative.
7. Conservation of Mechanical Energy
Energy comes in many forms and for any system can never be created or destroyed. This holds true for mechanical energy, which also obeys this law of conservation of energy. In this video lesson, you'll explore how mechanical energy is converted or transferred between forms and objects.
8. Power: Definition and Mathematics
Work involves moving an object with a force, but power tells us how quickly that work is done. In this lesson, you will learn about how power depends on both work and time as well as see examples of how to calculate power.
