About This Chapter
OAE Integrated Science: Work, Power & Energy - Chapter Summary
This chapter will help you recall the formal definitions of work, power and energy. It explores examples and characteristics of each while also giving you real-world applications of each concept. The lessons also feature examples of mathematical problems involving the three. By the end of the chapter, you will have covered:
- The definitions, characteristics, and examples of work, power and energy
- Work and variable forces
- Kinetic versus potential energy
- The work-energy theorem
- Mechanical versus thermal energy
- The mathematics of power
- How heat transfer works
You can study for your upcoming exam by watching our video lessons. You can then evaluate your knowledge of the material through our practice questions. Each lesson features these short quizzes, and the questions themselves are modeled after those on the exam in order to help you gain familiarity with your test format.
Objectives of the OAE Integrated Science: Work, Power & Energy Chapter
This chapter of our comprehensive study guide connects to the physical science domain of the OAE Integrated Science exam. This domain is the largest one on the entire test; it accounts for about 37% of the 150 multiple-choice questions on the exam. Questions on force, motion, and energy can be found in this domain. The OAE Integrated Science exam is 180-minutes long and computer based. Our study guide is also computer based and it will help you practice budgeting the correct amount of time to each one of the exam questions.
1. 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.
2. 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.
3. 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.
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. 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.
7. 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.
8. What is Mechanical Energy? - Definition & Examples
In physics, energy is how work gets done. This video describes one important type of energy, mechanical energy, and provides examples of both kinetic and potential mechanical energy.
9. What is Thermal Energy? - Definition & Examples
This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.
10. Mechanisms of Heat Transfer: Conduction, Convection & Radiation
There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.
