Addition of cectors. Draw the result of the following vector additions: (a) Add a vector $2 \mathrm{~cm}$ east to one $3 \mathrm{~cm}$ northwest. (b) Add a vector $8 \mathrm{~cm}$ east to one $12 \mathrm{~cm}$ northwest. (c) Compare the results of parts $(a)$ and $(b)$, and frame a theorem about adding a pair of vectors that are multiples of another pair.

Key Concepts

Linearity of Vector Operations

The linearity of vector operations refers to properties such as additivity and homogeneity, meaning that the sum of scaled vectors is equal to the scale of the sum of original vectors. In other words, if each component vector is multiplied by a constant, the overall vector sum is multiplied by that same constant. This principle is fundamental in vector algebra and appears in many applications, including the analysis of forces and displacements.

Scalar Multiplication

Scalar multiplication involves multiplying a vector by a constant (a scalar), thereby scaling the vector’s magnitude without altering its direction. This concept is essential for understanding how vectors can be proportionally increased or decreased, and it plays a critical role when comparing vectors that are multiples of one another.

Vector Addition

Vector addition is the process of combining two or more vectors to form a resultant vector, which reflects the cumulative effect of the original vectors in both magnitude and direction. It is typically visualized using methods such as the head-to-tail method or the parallelogram rule, which help in understanding how the individual vectors contribute to the overall result.
