Energy is one of the most fundamental concepts in many scientific fields. Learn more about its different types, subsequently testing your knowledge with a quiz.

Insulation: Definition & Uses

2. Insulation: Definition & Uses

This lesson is about insulation, which you might be familiar with in your home. However, there are other uses for insulation and here we'll talk about what each of those are, as well as what can technically be considered an insulator.

Constant Motion in Physics: Definition & Overview

3. Constant Motion in Physics: Definition & Overview

In this lesson you will learn about the different kinds of constant motion in physics. There are two types of constant motion relevant to physics: constant speed and constant acceleration. In this lesson you will learn the definition of both motions and how they are graphically illustrated.

Convection in Science: Definition, Equation & Examples

4. Convection in Science: Definition, Equation & Examples

In this lesson you will learn what convection is, go over an equation for convection, and see some examples of convection in everyday life, such as campfires and the Earth's outer core. A short quiz will follow.

Energy Transfer: Examples & Overview

5. Energy Transfer: Examples & Overview

Learn about energy and how the sun provides the energy needed to sustain life on Earth. Discover energy transfer and how energy is neither created nor destroyed, but moves from one place to another or changes from one form to another.

Find Displacement: Definition & Equation

6. Find Displacement: Definition & Equation

In this lesson, you will learn about displacement, the properties associated with it, the equation needed to calculate displacement, and some simple examples of the calculations.

Force in Physics: Definition & Examples

7. Force in Physics: Definition & Examples

Physical forces are all around us. Learn the defining characteristics of forces in physics, look at some examples, and test your understanding with a short quiz.

Gamma Radiation: Definition, Uses & Equation

8. Gamma Radiation: Definition, Uses & Equation

In this lesson you will learn what gamma radiation is. We will explore where it comes from, how we as humans make use of it, as well as its effect on the human body.

Heat Capacity: Definition & Equation

9. Heat Capacity: Definition & Equation

This lesson covers the topic of heat capacity, which is a core concept of thermodynamics. We will review the definition of heat and explore how it relates to an object's heat capacity.

Heat of Fusion: Definition, Equation & Examples

10. Heat of Fusion: Definition, Equation & Examples

This lesson will examine the heat of fusion, which is the energy required for matter to change between a liquid and a solid. In this lesson, we review the concepts of latent heat and work through a problem using our new understanding of the heat of fusion.

Heat of Vaporization: Definition & Equation

11. Heat of Vaporization: Definition & Equation

In this lesson, you'll learn about the heat required to transform a liquid to its gas phase. Specifically, we'll explore the factors affecting heat of vaporization, including how to estimate it and how it changes between different substances.

Inertial Frame of Reference: Definition & Example

12. Inertial Frame of Reference: Definition & Example

Learn how to tell the difference between an inertial frame of reference and a non-inertial frame of reference. Then find out what these frames of reference have to do with Newton's first law and fictional forces.

Joule: Units & Fractions

13. Joule: Units & Fractions

This lesson defines the metric unit for energy, the joule. The lesson also includes examples of the correct way to communicate fractions of a joule in addition to conversion of the joule into other energy units by the factor-label method.

Kinetic Energy: Examples & Definition

14. Kinetic Energy: Examples & Definition

To knock down a set of bowling pins, what must be true about the bowling ball? It must be moving! This lesson discusses the energy perspective of this simple truth: kinetic energy.

Latent Heat: Definition, Formula & Examples

15. Latent Heat: Definition, Formula & Examples

Heat is an important component of phase changes. This lesson will delve into the concept of latent heat and how it affects of the behavior of matter during phase changes.

Neils Bohr: Discovery & Biography

16. Neils Bohr: Discovery & Biography

Read about one of the most important contributors to modern physics, Niels Bohr. The Danish scientist led a fascinating life devoted to science, but also to peace after escaping Nazi-occupied Europe in the 1940s.

Perpetual Motion: Definition & Overview

17. Perpetual Motion: Definition & Overview

In this lesson you will learn about the idea of perpetual motion. You will see that perpetual motion is related to the idea of conservation of energy, machine efficiency, and thermodynamics. You will learn whether it is possible to have machines run under the principle of perpetual motion.
