- Energy and its natural occurrence
- Work as done by a variable force
- Applications of the work-energy theorem
- Relationships between different energy types, including kinetic to potential energy
- Conservative forces and conservation of mechanical energy
- Mathematical principles of power
Each video lesson is enhanced by our unique tagging system, which makes jumping to the topics you need to study easy and efficient.
Objectives of the GACE Physics: Work and Energy Chapter
The topics in this chapter will qualify your knowledge as well as teach you new or unfamiliar concepts in the relationships between energy and work. The GACE Physics test assesses your knowledge and understanding of scientific concepts based on a 6-12 grade level of comprehension of physics in order to determine your ability to teach this subject in the state of Georgia.
Information about energy production is part of in the Mechanics section, which composes 60% of test one. Our self-assessment quizzes that accompany each lesson will test your comprehension of the information covered in the exam and also give you insight to the question format you'll actually see on the day of the test.
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. 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.
5. 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.
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.
