About This Chapter
Electrical Forces and Fields - Chapter Summary and Learning Objectives
This chapter's video lessons can show you how electrically charged subatomic particles determine an object's electrostatic force and conductivity. Learn how to illustrate these concepts with an electric field diagram and identify units of measurement for electric charge. By the end of this chapter, you should be familiar with the following:
- Atomic properties of electric charge
- Effects of particle distance on force
- Factors affecting a material's conductivity
|Electric Charge and Force: Definition, Repulsion & Attraction||Introduces the atom, electrons and protons. Lesson content also discusses why some materials become charged, as well as why like charges repel and opposite charges attract.|
|Electric Force Fields and the Significance of Arrow Direction & Spacing||Expands the idea of repulsion and attraction into a field model before discussing the significance of the arrow direction and spacing used to indicate particle charge and the strength of an electrical field.|
|Coulomb's Law: Variables Affecting the Force Between Two Charged Particles||Examines the variables that affect the force between two charged particles and introduces the Coulomb as a unit of charge.|
|Insulators and Conductors: Examples, Definitions & Qualities||Describes qualities that make a material a good conductor or insulator of electricity and heat. Examples of common conductors and insulators are also provided.|
|Gauss's Law||Explains the relationship between an object's electric charge, permittivity and electric flux.|
1. Electric Charge and Force: Definition, Repulsion & Attraction
Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!
2. Electric Force Fields and the Significance of Arrow Direction & Spacing
Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.
3. Coulomb's Law: Variables Affecting the Force Between Two Charged Particles
In the 18th century, Charles Coulomb uncovered the secrets of electrostatic force between charged particles. The results of his experiments led to what is now known as Coulomb's Law, which tells us how force, charge, and distance are all related.
4. Insulators and Conductors: Examples, Definitions & Qualities
In this lesson, we'll explore the reasons that some materials conduct electrical energy with ease while others block it almost completely. We'll also talk about the property of conductivity and some everyday examples of insulators and conductors.
5. Gauss' Law: Definition & Examples
After watching this video, you will be able to explain what Gauss' Law is, derive Gauss' Law for a sphere and cylinder, and use it to solve problems. A short quiz will follow.
