# Ch 26: Vectors & Scalars in Math

### About This Chapter

## Vectors & Scalars in Math - Chapter Summary

In this chapter, our instructors present you with vectors in physics and demonstrate how they can be manipulated in math. These interesting lessons explain the difference between scalars and vectors and show you how to use geometry to add vectors. You'll review basic calculations involving scalar multiplication and understand how to find the cross product of two vectors. Other topics include the triple scalar product, which occurs when you multiply three vectors together. This informative chapter prepares you to do the following:

- Graph vectors with regard to direction and magnitude
- Add, subtract, multiply and divide vectors
- Find the dot product of vectors using algebra and geometry
- Calculate the direction of a vector when given the
*x*and*y*components

### 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. Scalars and Vectors: Definition and Difference

In this lesson, we will examine scalars and vectors, learn why it is important to know the difference between the two and why remembering to add a direction to many of your exam answers could be the reason you get it right or wrong.

### 3. Graphing Vectors in Math: Magnitude & Direction

Vectors are some of the most useful parts of math, but their usefulness is only apparent if you know how to graph them. In this lesson, we learn how to graph vectors with respect to both magnitude and direction.

### 4. Vectors in Math: Addition, Subtraction, Division & Multiplication

From airplanes to walking in a straight line, vectors are everywhere. In this lesson, we're going to learn how to add, subtract, multiply, and divide vectors helping us make more sense of them.

### 5. 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.

### 6. Scalar Multiplication of Vectors: Definition & Calculations

After watching this video, you will be able to explain what scalar multiplication is and complete basic calculations involving the scalar multiplication of vectors. A short quiz will follow.

### 7. Performing Operations on Vectors in the Plane

After watching this video lesson, you should be able to add, subtract, and multiply your vectors. Learn how easy it is to perform these operations and what you need to keep in mind when performing these operations.

### 8. The Dot Product of Vectors: Definition & Application

After watching this video lesson, you will be able to find the dot product of vectors both algebraically and geometrically. Learn the difference between the two and what you need in order to calculate them.

### 9. Finding The Cross Product of Two Vectors

After watching this lesson, you will be able to explain what a cross product is and calculate the cross product of two vectors. A short quiz will follow.

### 10. Vector Components: The Direction of a Vector

After watching this lesson, you will be able to explain what is meant by the direction of a vector and calculate the direction of a vector when given the x and y components. A short quiz will follow.

### 11. Triple Scalar Product: Definition, Formula & Example

Vectors and scalars are often discussed in physics. In this lesson, we define a particular multiplication of three vectors called the triple scalar product and use an example to show how it is calculated.
