# Ch 2: Overview of Vectors

### About This Chapter

## Overview of Vectors - Chapter Summary

Follow along with our expert physics instructors to review fundamental vector topics in the study of physics. Each lesson breaks down vector-related concepts in a simple and easy-to-understand manner. You can expect to study basic vector types and operations. Use the interactive lesson quizzes to help you practice solving vector problems on your own. Study the chapter at any time that fits your schedule, and feel free to reach out to our instructors if you have any questions about the material. When you're finished with the chapter, you should be able to:

- Recognize different types of vectors
- Use the geometric approach for vector addition and subtraction
- Apply various components to perform vector operations
- Identify standard basis vectors
- Calculate the resultants of vectors
- Add and subtract vectors

### 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. 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.

### 3. Vector Subtraction (Geometric): Formula & Examples

After watching this lesson, you will be able to subtract vectors geometrically and give examples of how that process might be used in physics. A short quiz will follow.
