Ch 4: AP Physics 1 Work, Energy, & Power: Homeschool Curriculum

About This Chapter

The work, energy, and power unit of this AP Physics 1 Homeschool course is designed to help homeschooled students learn about the relationships between work, energy, and power. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our AP Physics 1 Homeschool course will benefit any student who is trying to learn about the relationships between work, energy, and power. There is no faster or easier way to learn about work, energy, and power. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn about characteristics of work, types of energy, and how to calculate power.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a physics curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and a work, energy, and power unit exam confirm understanding or identify any topics that require review.

Work, Energy, and Power Unit Objectives:

  • Identify the characteristics of work.
  • Determine how much work is done by a variable force.
  • Learn what energy is and its role in nature.
  • Understand the relationship between potential energy and kinetic energy.
  • Discover the work-energy theorem and its applications.
  • Define and identify examples of mechanical energy.
  • Explore the types and mechanics of pulleys.
  • Learn about the conservation of mechanical energy.
  • Define power and understand how to calculate it.

9 Lessons in Chapter 4: AP Physics 1 Work, Energy, & Power: Homeschool Curriculum
Conservation of Mechanical Energy

1. 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.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

2. 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.

Power: Definition and Mathematics

3. 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.

Pulleys: Basic Mechanics

4. Pulleys: Basic Mechanics

Like other simple machines, pulleys can help us lift and move heavy loads with less effort. In this video lesson, you'll learn how pulleys do this as well as how this is possible while still obeying the law of conservation of energy.

What is Energy? - Definition and Significance in Nature

5. 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.

What is Mechanical Energy? - Definition & Examples

6. 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.

Work Done by a Variable Force

7. 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.

Work-Energy Theorem: Definition and Application

8. 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.

Work: Definition, Characteristics, and Examples

9. 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.
