  • Energy's significance in nature
  • Examples and characteristics of work
  • Connection of variable force to work
  • Work-energy theorem
  • Relationship between kinetic and potential energies
  • Gravitational potential energy

Kick back with your favorite device, and watch our video lessons anytime of the day or night. Use the lessons as many times as you like, and read the full transcripts as a backup or alternative. Track your progress with the multiple-choice quizzes, and if you're left with any questions, feel free to contact one of our subject-area experts.

ASVAB: Energy & Work Chapter Objectives

Along with the other portions of the 10-section test, the General Science subtest of the ASVAB helps to narrow down the most fitting jobs for military recruits. This subtest checks your knowledge of biological and physical sciences, including topics related to energy and work, and constitutes about 11% of the complete battery in the computerized or pencil and paper versions. Our optional multiple-choice assessments can help you rehearse questions similar to what you might find on the exam.

What is Energy? - Definition and Significance in Nature

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.

Work: Definition, Characteristics, and Examples

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.

Work Done by a Variable Force

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.

Work-Energy Theorem: Definition and Application

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.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

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.

Gravitational Potential Energy: Definition, Formula & Examples

6. Gravitational Potential Energy: Definition, Formula & Examples

In this lesson, you will learn what gravitational potential is, the equation we use to calculate it, and how to use that equation. We'll look at some real-life examples so you can see how it works. A short quiz will follow.
