Vectors are an essential concept in physics, mathematics, engineering, and computer science. They represent quantities that have both magnitude and direction, such as force, velocity, displacement, and acceleration. When working with multiple vectors, one of the most common operations is vector addition.

What Is Vector Addition?
Vector addition is the process of combining two or more vectors to determine a single resultant vector.
In a 2D coordinate system:
- Each vector has an X-component (horizontal direction)
- Each vector has a Y-component (vertical direction)
When adding vectors:
Rule of Vector Addition:
- Add all X-components together
- Add all Y-components together
The result is a new vector:
R = (Rx, Ry)
Where:
- Rx = X1 + X2
- Ry = Y1 + Y2
This resultant vector represents the combined effect of both original vectors.

Formula for Adding Vectors
Vector addition follows simple algebraic rules.
1. Resultant X Component
Formula:
Rx = X1 + X2
Explanation:
You add all horizontal components of vectors.
2. Resultant Y Component
Formula:
Ry = Y1 + Y2
Explanation:
You add all vertical components of vectors.
3. Magnitude of Resultant Vector
Once you find Rx and Ry, calculate magnitude using:
Formula:
|R| = √(Rx² + Ry²)
This is based on the Pythagorean theorem, which determines the length of the resultant vector.
Example of Vector Addition
Let’s understand vector addition with a practical example.
Given:
| Vector | X Component | Y Component |
|---|---|---|
| A | 3 | 4 |
| B | 5 | 6 |
Step 1: Add X Components
Rx = 3 + 5
Rx = 8
Step 2: Add Y Components
Ry = 4 + 6
Ry = 10
Step 3: Calculate Magnitude
|R| = √(8² + 10²)
|R| = √(64 + 100)
|R| = √164
|R| = 12.81
Final Result:
| Component | Value |
|---|---|
| Rx | 8 |
| Ry | 10 |
| Magnitude | 12.81 |
