Key Concepts

Vector Addition

Vector addition is the process of combining two vectors by adding their corresponding components. It is a fundamental operation in vector algebra used to determine the resultant vector when two or more vectors are combined.

Scalar Multiplication

Scalar multiplication involves multiplying every component of a vector by a scalar (a real number), effectively scaling the vector's magnitude while preserving or reversing its direction if the scalar is negative.

Vector Subtraction

Vector subtraction is the process of finding the difference between two vectors by subtracting their corresponding components. It is equivalent to adding the negative of a vector, and is used to determine relative displacement between two vectors.

Magnitude of a Vector

The magnitude of a vector, often referred to as its norm or length, is calculated using the Euclidean formula, which involves taking the square root of the sum of the squares of its components. This measure represents the distance of the vector from the origin in space.
