What Is a Vector?

A vector is a quantity that has both:

Magnitude (size or length)
Direction

Unlike scalar quantities, vectors describe movement or force in a specific direction.

Examples of Vectors

Quantity	Type
Velocity	Vector
Force	Vector
Acceleration	Vector
Displacement	Vector
Temperature	Scalar
Mass	Scalar

For example:

“10 meters” is a scalar
“10 meters north” is a vector

Understanding Vector Components

Vectors are often represented in coordinate form.

Example

Vector A:

$A=(x_1,y_1)$ A=(x1,y1)

Vector B:

$B=(x_2,y_2)$ B=(x2,y2)

Where:

x = horizontal component
y = vertical component

Vector Addition Formula

Vector addition combines two vectors into a single resultant vector.

Formula

$A+B=(x_1+x_2,\ y_1+y_2)$ A+B=(x1+x2, y1+y2)

Example

Vector A = (3, 4)
Vector B = (2, 5)

Calculation:

X-coordinate = 3 + 2 = 5
Y-coordinate = 4 + 5 = 9

Result:

A + B = (5, 9)

Vector Subtraction Formula

Vector subtraction finds the difference between two vectors.

Formula

$A-B=(x_1-x_2,\ y_1-y_2)$ A−B=(x1−x2, y1−y2)

Example

Vector A = (8, 6)
Vector B = (3, 2)

Calculation:

X-coordinate = 8 − 3 = 5
Y-coordinate = 6 − 2 = 4

Result:

A − B = (5, 4)

Dot Product Formula

The dot product measures how much two vectors point in the same direction.

Formula

$A\cdot B=(x_1x_2)+(y_1y_2)$ A⋅B=(x1x2)+(y1y2)

Example

Vector A = (2, 3)
Vector B = (4, 5)

Calculation:

(2 × 4) + (3 × 5)
8 + 15
23

Dot Product = 23

Magnitude Formula

Magnitude represents the length of a vector.

Formula

For Vector A:

$|A|=\sqrt{x_1^2+y_1^2}$ ∣A∣=x12+y12

For Vector B:

$|B|=\sqrt{x_2^2+y_2^2}$ ∣B∣=x22+y22

Example

Vector A = (3, 4)

Calculation:

√(3² + 4²)
√(9 + 16)
√25
5

Magnitude = 5

Angle Between Two Vectors Formula

The calculator also finds the angle between vectors.

Formula

$\cos\theta=\frac{A\cdot B}{|A||B|}$ cosθ=∣A∣∣B∣A⋅B

Where:

A·B = dot product
|A| = magnitude of vector A
|B| = magnitude of vector B

Vector A	Vector B	Addition	Subtraction	Dot Product	Magnitude A	Magnitude B
(2,3)	(4,5)	(6,8)	(-2,-2)	23	3.61	6.40
(1,1)	(2,2)	(3,3)	(-1,-1)	4	1.41	2.83
