AP Physics 1: Electrical Forces and Fields - Chapter Summary and Learning Objectives

You probably know that opposite force attract each other, but do you know why? In this chapter, our instructor will explain how the structure of atoms causes some materials to gain a charge. You'll learn about electric force fields and how to draw diagrams of the fields. You'll begin to make some calculations involving electrical forces, in particular using Coulomb's law to understand force in relation to the distance between charged particles. We'll also take a look at insulators and conductors and which materials are good in these roles. After completing this chapter, you should be able to:

  • Describe the change in atomic structure that results in an electric charge
  • Draw force field models around charged items
  • Use Coulomb's law to calculate magnitude of electrostatic force
  • Explain what properties make an insulator or conductor effective

Electric Charge and Force: Definition, Repulsion & Attraction

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!

Positive Charge: Definition & Overview

2. Positive Charge: Definition & Overview

Positive charges cause your hair to stand up on a cold day and can give you a shock when you touch a doorknob, but they also are responsible for holding atoms together. In this lesson, we'll learn what creates a positive charge and how it interacts with negative charges.

Negative Charge: Definition & Overview

3. Negative Charge: Definition & Overview

There are two types of charge, positive and negative. In this lesson, you will learn about how negative charges were assigned to electrons. You will also learn about the properties of negative charges and how they affect other objects near them.

Elementary Charge: Definition & Overview

4. Elementary Charge: Definition & Overview

What is the smallest amount of charge that can exist? In this lesson, learn the answer to the question! You will also learn about which atomic particles are charged and how charge is transferred from one object to another.

Using the Two-Charge Model of Electric Charge

5. Using the Two-Charge Model of Electric Charge

Electric charge has two varieties, positive and negative. In this lesson we will explore how the two-charge model of electric charge was created and see how it is applied.

Electric Force Fields and the Significance of Arrow Direction & Spacing

6. 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.

Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

7. 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.

Insulators and Conductors: Examples, Definitions & Qualities

8. 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.
