### About This Chapter

## AP Physics 2: Vector & Scalar Fields - Chapter Summary

This helpful chapter covers vectors, scalars and how both are used to make inferences so you can easily study for the AP Physics 2 exam. Each short video or text lesson is accompanied by a multiple-choice quiz you can use to test your understanding and see where you need to study further before the exam. You can use the video tabs feature to quickly jump forwards or backwards in a video lesson to just the spot you'd like to watch. If you need assistance as you review the lessons, feel free to contact an instructor. This chapter is designed to assist you to:

- Identify the different types of vectors
- Explain what vector diagrams are used for
- Describe the geometric approach to vector addition
- Make inferences using vector and scalar fields
- Give examples of scalar quantity as its defined in physics
- Detail the uses for scalar addition
- Use scalar fields to make inferences

### 1. What Is a Vector? - Definition & Types

After watching this lesson, you will be able to explain what vectors are in physics, give some examples of vectors and have a basic idea of how they can be manipulated mathematically. A short quiz will follow.

### 2. What are Vector Diagrams? - Definition and Uses

After watching this video, you will be able to explain what vector diagrams are and how they are used, including vector addition and subtraction. A short quiz will follow.

### 3. Vector Addition (Geometric Approach): Explanation & Examples

After watching this video, you will be able to explain why we might need to add two vectors and, given magnitudes and directions, add two vectors using geometric methods. A short quiz will follow.

### 4. Scalar Quantity in Physics: Definition & Examples

In this lesson, you will learn about what makes a number a scalar quantity. You will learn how to identify quantities that are scalars from those that are not scalar quantities. You will also learn about numbers that don't look like scalars but are actually scalars.

### 5. Scalar Addition: Definition, Uses & Example

There are some quantities in physics that can be easily added via scalar addition without having to worry about the direction of the quantity. Learn about this along with how the addition works in this lesson.
